The .geo file format belongs to Trumpf’s TruTops suite, the CAM software that drives TruLaser, TruPunch, and TruMatic sheet metal machines. It stores 2D part geometry for laser cutting and punching: outer and inner contours, bend data, material type, and thickness.

Outside the Trumpf ecosystem, almost nothing opens it. Generic CAD programs don’t recognize the format. Online converters either skip it or silently fail. Forum threads going back more than a decade end with the same two answers: go back to the shop that made the file, or license TruTops Convert from Trumpf.

Starting with version 8.0.200, reaConverter reads Trumpf GEO files directly and exports them to DXF, ready for AutoCAD, SolidWorks, Fusion 360, Bystronic BySoft, Amada AP100, or any other CAD or CAM system that speaks DXF.

Step-by-Step: GEO to DXF Conversion

The manual workflow takes under a minute, regardless of how many files are in the batch.

1. Install or Update reaConverter 8

Download the latest version from reaConverter.com. GEO support requires version 8.0.200 or later.

2. Add Your GEO Files

Drag your .geo files into the main window, or use Add Folder to load an entire parts directory at once. reaConverter processes large batches in a single pass with no file count limits.

3. Select DXF as the Output Format

In the output panel, choose DXF. Set your destination folder and any file-naming convention you want to apply.

4. Start Conversion

Click Start. reaConverter reads each GEO file, extracts the geometry, and writes a standards-compliant DXF.

Open the results in AutoCAD, LibreCAD, SolidWorks, Fusion 360, BricsCAD, or feed them directly into your CAM system.

Who This Is For

Job shops with used or second-hand Trumpf equipment. You bought a TruLaser off the auction market and inherited hundreds of legacy GEO parts. The machine runs. The files are locked inside a format your current CAD system doesn’t open.

Subcontract fabricators. A customer sends you GEO files because that’s what their engineering department exports. You run a Bystronic or an Amada. You need DXF.

Engineers migrating between CAM platforms. Your shop is standardizing on a different system, but you have years of part geometry sitting in GEO. Rebuilding from scratch isn’t an option.

Anyone who received a GEO file and needs to open it. Sometimes a customer, a vendor, or a colleague sends a file in a format their software exports by default. You don’t need to match their software stack. You need to read the file.

Batch Conversion for Legacy Libraries

Inherited parts libraries often contain hundreds or thousands of files. Manual conversion isn’t viable at that scale. reaConverter processes the entire folder in one pass and preserves the original directory structure if you want it to.

For shops that receive GEO files on an ongoing basis, such as subcontractors working with Trumpf-equipped customers, Watch Folders automate the conversion entirely. Point reaConverter at a hdd folder, set DXF as the output, and any GEO file that lands there gets converted automatically. Nobody has to launch the application or click anything.

Command-line support is available for IT teams integrating GEO conversion into ERP workflows, scheduled parts-library migrations, or customer file intake pipelines. Both features are available in reaConverter Pro.

Why GEO Is Hard to Convert

TruTops GEO is a proprietary 2D geometry format. It stores outer and inner contours, bend lines, cut types, and material properties in a structure that only Trumpf’s own software documents fully. There’s no public specification. The format was designed for round-tripping inside the Trumpf ecosystem, not for interoperating with third-party CAD.

That’s why most conversion attempts fail. Generic DXF libraries don’t understand the structure. Even technically capable users reaching for open-source tools come up empty.

reaConverter parses the GEO contour and geometry data directly and writes a clean DXF with the outlines preserved, ready to import into any standard CAD or CAM workflow.

Alternatives and Where Each Fits

TruTops Convert is Trumpf’s own conversion utility. It’s the right choice for shops running Trumpf machines and already using the TruTops suite. For everyone else — shops on other CAM platforms, subcontractors processing occasional incoming GEO files, or teams migrating away from TruTops — it’s more software than the job requires.

Re-exporting from the source CAD. The standard forum advice is to ask whoever generated the GEO file to export DXF instead. Sometimes that works. Often the source isn’t reachable, the customer isn’t responsive, or the parts were generated years ago by a shop that no longer exists.

Manual redrawing. Feasible for a handful of simple parts. Not feasible for a library of hundreds.

reaConverter sits in the space these options leave open: direct GEO reading, batch processing, offline, on any Windows machine.

Background

This feature was built in response to a direct customer request. A shop running Trumpf equipment hit a conversion failure on a specific GEO file and asked whether we could handle the format. We obtained sample files, built the extraction logic, and shipped support in reaConverter 8.0.200. The customer’s response after testing:

“FROM TRUMPF TO DXF. IS GO WELL. MASSIVE THANKS.”

If your workflow involves Trumpf GEO files and you need them as DXF — reliably, in batch, on Windows — reaConverter handles it.

Why convert DWG to DXF?

DWG is the native binary format of AutoCAD. It’s powerful, but proprietary. When you need to share drawings with partners who use SolidWorks, BricsCAD, FreeCAD, LibreCAD, or any non-Autodesk CAD tool, the proprietary DWG container becomes a bottleneck. DXF (Drawing Exchange Format) was designed specifically to solve this: it’s an open, documented interchange format that virtually every CAD program can read and write.

Common real-world scenarios where DWG → DXF conversion is essential:

• Cross-platform collaboration with partners who use SolidWorks, BricsCAD, FreeCAD, or other non-Autodesk CAD tools.
• CNC and laser cutter pipelines that accept only DXF input.
• Archival and compliance requirements where an open format avoids vendor lock-in.
• Automated production workflows where DWG files must be converted before entering a review or manufacturing system.

If you’re converting one or two files, an online tool might do. But when the job involves hundreds of drawings on a recurring basis, you need batch automation that runs offline, keeps your intellectual property on your hardware, and doesn’t require an expensive AutoCAD seat.

That’s where reaConverter comes in.

DWG vs DXF — quick reference

What you’ll need

• reaConverter Standard edition is enough for GUI batch conversion. For Watch Folders and command-line automation, you’ll need Pro. See the DWG to DXF conversion page for a quick overview of what’s supported.
• Your .dwg files. reaConverter supports all AutoCAD versions from R12 through the latest releases.
• No AutoCAD installation is required at any point.

Method 1 — Batch conversion in the GUI

This is the fastest way to convert a folder of DWG files interactively.

Step 1. Add your DWG files

Launch reaConverter and load your drawings. You can:

• Drag-and-drop files or entire folders from Windows Explorer.
• Use the Add Files or Add Folder buttons on the toolbar.
• Right-click DWG files in Explorer and choose Convert with reaConverter from the context menu.

reaConverter reads DWG natively, no CAD software needed. The file list shows previews, page count, and size for every drawing.

Step 2. (Optional) Configure DWG loading settings

Before converting, you can fine-tune how drawings are read:

• Layout selection: convert Model Space only, all Paper Spaces, or all layouts. Look for the DXF/DWG/DGN loading settings in the Settings panel on the left side of the main window.
• Grayscale: render the drawing in grayscale if color is not needed downstream.
• Layer extraction: split each layer into a separate output file.

These settings are especially useful when your DWG files contain multiple layouts and you only need the Model Space geometry.

Step 3. Choose DXF as the output format

In the bottom panel, set Save as → DXF. Click the gear icon next to DXF to open format-specific settings:

• DXF version: choose from AutoCAD 12, 13, 14, 2000, 2004, 2007, 2010, or 2013. If unsure, AutoCAD 2000 offers the best balance of compatibility and feature support.
• Units: millimeters or inches.
• Text handling: save as text or convert to polygons (useful when downstream tools have font substitution problems).
• Splines: enable or disable spline output.

Step 4. Set the destination folder

Choose where converted DXF files should be saved. You can keep the same folder structure as the source, save everything to a flat folder, or use reaConverter’s subfolder naming options.

Step 5. Click Convert

Hit Convert and reaConverter processes every file in the queue. The conversion log shows the status of each drawing. When done, click Show converted files to jump straight to the output folder.

Install reaConverter

Method 2 — Watch Folders (fully automated, zero clicks)

Watch Folders turn any Windows directory into a self-converting hot folder. Drop a DWG file in → a DXF file appears in the output directory. No interaction needed.

This is the ideal setup for:

• Engineering offices where designers save DWG files to a shared network folder and downstream teams need DXF.
• CNC / fabrication pipelines where an operator drops files for cutting.
• Any recurring workflow where manual conversion is a bottleneck.

How to set it up

1. Open reaConverter and go to Menu → Watch Folders → Add new folder…
2. Set the Source folder — this is the directory reaConverter will monitor, for example C:\CAD\DWG_inbox\.
3. Set the Output folder — for example C:\CAD\DXF_ready\.
4. Choose DXF as the output format and configure version, units, and other settings as described in Method 1.
5. Click Start Watching.

From now on, every DWG file that lands in the source folder will be automatically converted to DXF and placed in the output folder. It doesn’t matter how the file got there: copied manually, saved by a CAD tool, or synced from the network.

reaConverter keeps running in the background and can monitor multiple folder pairs simultaneously.

Tip: Use “Subfolder of source folder” output option combined with “Read subfolders” to maintain your directory structure while keeping originals separate from converted files.

For a detailed walkthrough, see the dedicated guide: A Beginner-Friendly Guide to reaConverter’s Watch Folders.

Method 3 — Command-line conversion

reaConverter Pro includes cons_rcp.exe, a full-featured command-line tool. It accepts the same parameters as the GUI and can be called from batch scripts, CI/CD pipelines, PowerShell, or Task Scheduler.

Basic single-file conversion

cons_rcp.exe -s "C:\Drawings\floorplan.dwg" -o "C:\Output\floorplan.dxf"

Batch convert an entire folder

cons_rcp.exe -source_folder "C:\Drawings\" -source_ext dwg -dest_path "C:\Output\" -dest_ext dxf

This converts every .dwg file in the source folder and saves each one as .dxf in the output folder.

With subfolders

cons_rcp.exe -source_folder "C:\Drawings\" -source_ext dwg -dest_path "C:\Output\" -dest_ext dxf -read_subfolders 1

Set the output DXF version

Use -dxf_version to target a specific AutoCAD version:

Convert to AutoCAD 2000 DXF format:

cons_rcp.exe -source_folder "C:\Drawings\" -source_ext dwg -dest_path "C:\Output\" -dest_ext dxf -dxf_version 4

Control layout output

Use -dxf_dwg_layout to specify which layout to convert:

Export only Model Space:

cons_rcp.exe -source_folder "C:\Drawings\" -source_ext dwg -dest_path "C:\Output\" -dest_ext dxf -dxf_dwg_layout 1

Additional useful parameters

• -dxf_text 1 — preserve text as editable text (use 0 to convert text to polygons).
• -dxf_spline 1 — include splines in the output DXF.
• -dxf_units 1 — set output DXF units to millimeters (2 for inches).
• -dxf_dwg_gray 1 — convert the drawing to grayscale.
• -dxf_dwg_extract_layers 1 — extract each layer as a separate DXF file.
• -overwrite 1 — overwrite existing files instead of skipping them.
• /hide — run silently (no console window), ideal for scheduled tasks.

Full production example

Convert all DWG files (including subfolders) to AutoCAD 2000 DXF, Model Space only, with splines, millimeters as units, and overwrite existing output:

cons_rcp.exe -source_folder "D:\Projects\2026\CAD\" -source_ext dwg -dest_path "D:\Projects\2026\DXF\" -dest_ext dxf -read_subfolders 1 -dxf_version 4 -dxf_dwg_layout 1 -dxf_spline 1 -dxf_units 1 -dxf_text 1 -overwrite 1

Automate with Windows Task Scheduler

Save the command above as a .bat file and schedule it to run nightly, weekly, or at any interval. Add /hide to suppress the console window. Use > log.txt to capture the conversion log:

cons_rcp.exe -source_folder "D:\Projects\2026\CAD\" -source_ext dwg -dest_path "D:\Projects\2026\DXF\" -dest_ext dxf -dxf_version 4 /hide > "D:\Logs\dwg_to_dxf_log.txt"

For the full CLI reference, see: Command-line Interface for Developers.

Troubleshooting

Layers missing after conversion? Check the layout setting. If you’re exporting only Model Space (-dxf_dwg_layout 1) but your geometry lives in a Paper Space layout, switch to All Layouts (0) or All Paper Spaces (2).

Text looks wrong or is replaced by boxes? The target system may not have the fonts used in the DWG. Two options: set -dxf_text 0 to convert text to polygons (preserves appearance but loses editability), or install matching SHX / TTF fonts on the receiving machine.

File size significantly larger than original? This is expected. DXF (especially ASCII DXF) is less compact than binary DWG. If size matters, check whether your downstream tool accepts binary DXF. reaConverter outputs ASCII DXF by default for maximum compatibility.

Which reaConverter edition do I need?

Conclusion

Converting DWG files to DXF doesn’t require AutoCAD, doesn’t require uploading your proprietary drawings to the cloud, and doesn’t have to be a manual file-by-file task. reaConverter handles the job in three ways: GUI batch, Watch Folders, and command line. Whether you need a one-off conversion or a fully automated 24/7 pipeline, you’re covered.

For engineering firms, architecture studios, fabrication shops, and anyone working with CAD drawings at scale, this is the workflow that eliminates the bottleneck. Already know what you need? Head straight to the DWG to DXF converter page to download or try online.

Extract individual frames from embedded multiframe DICOM — no scripting, no manual splitting

Multiframe DICOM files pack dozens or even hundreds of image frames into a single container. CT volumes, MRI sequences, ultrasound cine loops, and nuclear medicine studies are commonly stored this way. When a downstream system, analysis pipeline, or colleague expects one-image-per-file DICOM, you’re stuck — most conversion tools either ignore the extra frames or don’t offer DICOM as an output format at all. The usual alternatives are writing Python scripts with pydicom, wrestling with dcmtk command-line utilities, or paying for specialized medical imaging software.

A recent customer request summed up the problem:

“My goal was converting from an embedded DICOM multiframe file to multiple single-frame files, but there was no such option.”

Starting with version 8.0.200, reaConverter supports direct DICOM to DICOM conversion, including full extraction of frames from both classic and Enhanced multiframe DICOM files.

Download reaConverter

Classic vs. Enhanced Multiframe DICOM

Multiframe DICOM comes in two flavors. Classic (Simple) Multiframe is the older format where all frames share one set of metadata(common in legacy archives and ultrasound systems). Enhanced Multiframe is the modern standard for CT and MRI, where each frame carries its own metadata through Functional Group sequences — more capable, but significantly harder for third-party software to parse. Most DICOM tools either don’t support Enhanced multiframe at all, or only extract the first frame. If your file contains multiple images and you need to separate each frame into its own DCM file, reaConverter handles both types.

Who This Is For

Radiologists and imaging departments — Separate multiframe CT, MRI, or ultrasound studies into individual slices for viewers that require single-frame input. Prepare data for second opinions or external consultations where the receiving system doesn’t support multiframe.

Medical researchers and AI developers — Convert multiframe studies into single-frame datasets for machine learning training and image analysis pipelines. Most ML frameworks expect one image per file; multiframe DICOM breaks that assumption.

PACS engineers and healthcare IT — Migrate imaging data between systems with different multiframe support. Normalize mixed archives. Handle extensionless DICOM files exported from older equipment without manual preprocessing.

Step-by-Step: Multiframe DICOM to Single-Frame DCM

Follow these steps:

1. Install or Update reaConverter 8

Download the latest version from reaConverter.com. DICOM-to-DICOM conversion requires version 8.0.200 or later.

2. Add Your Multiframe DICOM Files

Drag files into the main window, or use Add Folder to load an entire study directory.

reaConverter detects DICOM files automatically — with standard extensions (.dcm, .dic, .dicom) or without any extension at all, based on the DICOM header. Extensionless DICOM is extremely common in PACS exports and scanner-generated archives. No renaming needed.

3. Select DCM as the Output Format (DICOM to DCM Conversion)

In the output format panel, choose DCM. This is a DICOM-to-DICOM conversion: the input is your multiframe file, the output is a set of individual single-frame DICOM files.

4. Start Conversion

Click Start. reaConverter will:

• Detect the multiframe structure inside each input file
• Extract every frame
• Save each frame as a separate single-frame DCM file

Output files are named sequentially:

pacient_scan_001_frame_001.dcm
pacient_scan_001_frame_002.dcm
pacient_scan_001_frame_003.dcm
...

No additional settings, filters, or scripting required.

Clinical-Grade Output: UIDs and Header Remapping

Splitting a multiframe file is only half the job. For the output to work in a PACS or treatment planning system, two things have to happen under the hood — and most general-purpose converters skip both.

Unique SOPInstanceUID per frame. Every DICOM instance needs its own globally unique SOPInstanceUID. reaConverter generates a fresh, standards-compliant UID for every single-frame file it writes, so PACS systems don’t reject, overwrite, or silently deduplicate the output.

Functional Group Sequence remapping. Enhanced multiframe stores per-frame metadata inside Shared and Per-Frame Functional Group Sequences. Legacy single-frame readers don’t know where to look for it. reaConverter extracts those attributes and writes them into the top-level header of each output file, producing legacy-compatible DICOMs that load correctly in older viewers and PACS archives.

These two steps are the reason teams often fall back to command-line tools like dcm4che‘s emf2sf. reaConverter delivers equivalent output through a standard Windows GUI, with batch processing and Watch Folder automation on top.

Beyond Multiframe Extraction

reaConverter doesn’t only split multiframe DICOM into single-frame DCM. You can also:

• Convert multiframe DICOM to JPEG, PNG, TIFF or PDF for visualization, presentations, or reporting
• Batch-process large imaging archives with hundreds of studies
• Convert other medical and non-medical formats to DCM

Save Hours with Automatic Conversion

The four steps above work when you need to convert a batch of files once. But in a busy radiology department or research lab, multiframe DICOM files keep arriving — from scanners, PACS exports, external referrals. Converting them manually every time means someone has to stop what they’re doing, and that someone usually has patients waiting.

Watch Folders eliminate that step entirely. You pick a folder on your computer, tell reaConverter what format you want, and that’s it. From that point on, any file that lands in that folder gets converted automatically. No clicks, no application window, nothing to remember.

Here’s what that looks like in practice: your MRI scanner exports a multiframe Enhanced DICOM study into a shared network folder. Within seconds, reaConverter detects the new file, splits it into single-frame DCMs, and places the results in your output folder — ready for your PACS, your analysis pipeline, or your colleague down the hall. Nobody had to open anything or press any buttons.

Setting it up takes about two minutes:

1. In reaConverter Pro, go to Menu → Watch Folders → Add New Folder
2. Point it at your input directory
3. Choose DCM as the output format
4. Set a destination folder

That’s the entire configuration. It runs quietly in the background from that point forward.

For a radiologist reviewing 20–30 studies a day, or a research team processing imaging data from multiple sites, this turns a recurring manual task into something that simply doesn’t exist anymore. That’s one less thing standing between a scan and a diagnosis.

Command-line support is also available for IT teams who want to integrate DICOM conversion into scripts, scheduled tasks, or PACS migration workflows. Both options are available in reaConverter Pro.

Background

This feature was built in response to a direct customer request. A user reached out explaining that they needed to extract individual frames from embedded multiframe DICOM files, and couldn’t find a way to do it in reaConverter or anywhere else without resorting to scripting.

We obtained sample files covering both classic and Enhanced multiframe DICOM, including extensionless files from PACS exports, and built extraction logic that handles all of these cases reliably. DICOM-to-DICOM conversion shipped in reaConverter 8.0.200.

Full support for Enhanced multiframe DICOM extraction is still uncommon, even in professional medical imaging software. Many tools handle classic multiframe but fail on Enhanced, or extract only the first frame, or simply don’t offer DICOM as an output format. reaConverter fills that gap: no DICOM dictionary edits, no Python scripts, no per-frame configuration. Load the file, pick DCM, click Start.

If your imaging workflow involves multiframe DICOM files and you need them split into individual frames, reliably, in batch, with no manual intervention, reaConverter handles it.

Get reaConverter and split your first multiframe DICOM in seconds.

Batch convert Zeiss DCM to PDF — no more one-by-one exports

Eye care clinics using Zeiss Forum face a persistent workflow problem: when another provider requests patient data, the only export option is DICOM — a format most recipients can’t open. Staff end up downloading PDFs one at a time, sometimes 50 or more per patient.

reaConverter 8 now includes dedicated support for Zeiss Forum DICOM files, including the non-standard embedded PDFs that cause other converters to fail.

Download reaConverter

Why Zeiss DICOM Files Are Different

Standard DICOM converters often can’t read Zeiss Forum exports. That’s because Zeiss stores PDFs inside DICOM containers using a proprietary structure that doesn’t follow typical DICOM conventions.

The result: your conversion software reports “Reading file… Fail” even though the data is intact inside the file.

reaConverter detects these Zeiss-specific structures and extracts the embedded content correctly.

What You Can Convert To

• PDF — for referrals, insurance, and external providers
• JPG, PNG — for individual images
• TIFF — for archival quality

All formats support batch processing — convert entire folders at once.

Step-by-Step DCM to PDF Conversion

Follow these steps:

1. Install reaConverter 8

Download the latest version from reaConverter.com. Zeiss DICOM support requires version 8.0.184 or later.

2. Add Your DCM Files

Drag your .dcm files into the main window, or use Add Folder to load an entire export directory.

3. Select Output Format

Choose PDF for most sharing scenarios. The output panel lets you set destination folder and naming conventions.

4. Click Start

reaConverter reads the Zeiss DICOM structure, extracts embedded documents, and writes them to your chosen format. No manual steps required.

Who This Helps

This feature addresses a specific need for:

• Ophthalmology and optometry practices using Zeiss Forum
• Medical records staff handling inter-provider transfers
• IT administrators managing clinical data workflows

If your clinic regularly shares Zeiss imaging data externally, batch DICOM conversion eliminates hours of repetitive manual exports.

Automation Options

For high-volume clinics or IT teams managing multiple Zeiss workstations, reaConverter offers additional automation capabilities:

Watch Folders — Set up a monitored folder that automatically converts any new DCM files as they arrive. Drop Zeiss exports into the folder and get PDFs out without launching the application.

Command Line Support — Integrate DICOM conversion into existing scripts, scheduled tasks, or backup workflows. Automate nightly batch processing or trigger conversions from your practice management system.

Both options are available in reaConverter Pro, making it possible to build hands-off conversion pipelines that require zero manual intervention.

Background

This feature was developed after a customer reached out about their Zeiss Forum workflow:

“When we get requests to send patient data to another provider, all we can do is download 10–50+ PDFs one at a time because Zeiss only allows for DICOM files on export, which nobody we deal with can use.”

We obtained sample files, identified the non-standard DICOM structure Zeiss uses, and built extraction logic that handles it reliably.

Conclusion

Converting Zeiss Forum DICOM to PDF using reaConverter eliminates one of the most time-consuming bottlenecks in ophthalmic data sharing. Instead of manually exporting dozens of files one at a time, you can batch process entire patient folders in minutes. Whether you’re handling a single referral or managing large-scale data transfers between providers, reaConverter gives you a reliable way to turn locked-down Zeiss DCM exports into standard, shareable formats — no workarounds required.

The 3MF (3D Manufacturing Format) has become one of the most modern and flexible formats in additive manufacturing. It can store not only the geometric mesh of your model, but also materials, textures, colors, print parameters, and metadata – all neatly packaged inside a compressed ZIP-based container.

However, despite its advantages, many 3D printers and slicing tools still rely on the STL format. STL remains the simplest and most widely supported geometry-only standard in 3D printing. For this reason, converting 3MF to STL is a frequent and necessary step in many production and prototyping workflows.

In this tutorial, we’ll look at how reaConverter processes 3MF files, how to control the conversion quality using Level of Detail, and how to export clean STL files ready for slicing.

Download reaConverter

Why Convert 3MF to STL?

There are several common reasons to convert 3MF files to STL:

• Printer or slicer compatibility: A number of consumer and older industrial 3D printers still do not fully support 3MF. STL guarantees near-universal compatibility.
• Geometry-only workflow: If your printing workflow requires only the mesh (triangular surface), STL is the simplest and most portable choice.
• Sharing and archiving: For many users, STL files remain the “common denominator” format that can be shared or archived without concerns about color or material data.

How reaConverter Handles 3MF Input

When you open a 3MF file in reaConverter, the software extracts the geometry of the model. Additional information such as:

• colors
• textures
• materials
• print profiles
• metadata

…is intentionally ignored, ensuring a clean, geometry-only workflow for STL export.

Supported geometry in 3MF

reaConverter interprets the following geometry types:

• Triangles
• Cylinders (converted to triangular mesh)
• Spheres (converted to triangular mesh)

If the 3MF already consists purely of triangles, conversion is straightforward.
If cylinders or spheres are present, reaConverter will tessellate them into triangles during the conversion.

Level of Detail (LOD): Controlling Mesh Quality

When converting curved surfaces (such as cylinders or spheres), reaConverter allows you to control the precision of the output mesh using: Loading settings → 3D formats loading settings → Level of Detail

This setting influences how finely curved shapes are tessellated.

• Higher Level of Detail
  • More triangles
  • Smoother curves
  • Larger STL file size
  • Best for visual precision or small curved objects
• Lower Level of Detail
  • Fewer triangles
  • More faceting on curves
  • Smaller STL files
  • Useful for rapid prototyping

If the source 3MF contains only triangles, this setting will have no effect, as no tessellation is needed.

How to Convert 3MF to STL in reaConverter

Follow these steps:

1. Add your 3MF files

Drag and drop files into reaConverter, or use the “Add Files” button.

Batch conversion is fully supported.

2. Adjust 3D format loading settings

Go to:
Menu → Loading Settings → 3D Formats Loading Settings → Level of Detail

Choose the detail level appropriate for your model:

• Low detail 1-3: Creates simplified models, perfect for quick previews, protecting design details, or reducing file sizes.
• Medium detail 4-5: Balanced quality for most general purposes.
• High detail 6-7: Maximum precision for manufacturing, detailed 3D printing, or when you need every curve and surface captured accurately.

3. Select the output format

On the “Save As” panel, choose STL.

4. Start the conversion

Press Convert and wait for reaConverter to generate STL files.

3MF to STL conversion workflow can also be automated using:

• Right-click conversion
• Watch Folders
• Command line interface

Pros and Cons of 3MF → STL Conversion

Advantages

• Maximum compatibility with 3D printers and slicers
• Clean geometry-only export
• Flexible detail control during tessellation
• Batch processing and automation via reaConverter

Limitations

• Loss of non-geometric data (colors, textures, materials)
• High LOD settings may produce large STL files
• Low LOD may result in faceted curves or loss of smoothness

Best Practices for High-Quality STL Output

• Choose a balanced Level of Detail for your specific model geometry.
• Visually inspect the STL after conversion to ensure surface smoothness.
• For production workflows, keep a record of which LOD level works best for different object types.
• Use Watch Folders to automatically process incoming 3MF files with predefined settings.
• If your slicer includes STL repair tools, run a quick validation of the mesh before printing.

When You Should Keep the File as 3MF

Although STL is more widely supported, you should avoid conversion when:

• You need to preserve color, texture maps, or material assignments
• Your printer or slicer natively supports 3MF
• You are working with workflows where metadata or print settings must remain intact

In these cases, 3MF is the superior format.

Conclusion

Converting 3MF to STL using reaConverter is an efficient and reliable way to prepare 3D models for printing on devices that do not support 3MF. By adjusting the Level of Detail, you can achieve the ideal balance between surface accuracy and file size. Whether you’re processing a single model or automating large-scale batch conversions, reaConverter provides a powerful toolkit for generating clean, ready-to-slice STL files.

Turn PDFs, TIFFs, CAD multi-page documents and other multipage files into a single, continuous image (vertically or horizontally) with reaConverter’s Merge to One Image option. This feature is particularly useful when converting to formats that don’t support multiple pages, or when you need scrollable visuals for easier viewing, sharing, or presentation purposes. Whether you’re handling scanned documents, technical drawings, or creating social media content, this tool streamlines your workflow by turning multiple pages into one cohesive file.

Download reaConverter

What is “Merge to One Image”?

Merge to One Image combines all pages of a multipage document (or multiple documents) into a single output image. Pages can be stacked vertically (one long scrollable image) or placed horizontally (wide panorama), preserving the visual fidelity of each page while making the result easier to view, share, or embed in presentations.

This feature is particularly useful when converting to image formats that don’t support multiple pages — such as JPG, PNG, or BMP. Instead of saving just the first page or creating separate files, Merge to One Image ensures all your content stays together in one continuous image.

Quick Step-By-Step Guide

1. Add files

Drag-and-drop your multipage files (PDF, TIFF, PLT, CGM, CG4, etc.) into reaConverter or use Add files / Add folder for batch processing.

2. Enable single-file output + Merge

Go to Saving Settings → Multipage files. Choose “Save all processed files to one file” and tick “Merge to one image”. Then pick Vertically or Horizontally depending on whether you want a long vertical strip or a wide image.

3. Choose output format & quality

Select JPG/PNG/TIFF as needed and configure DPI/quality to balance fidelity and file size.

4. Convert

Click Convert to produce the single merged image. reaConverter will process the pages and generate the final file in your specified output folder.

Advanced Options and Batch Use

Batch processing: Add many multipage files or entire folders — the same Merge settings are applied to each job.

Group files into one image: If you need to control grouping (e.g., merge every N files into one image), use the “Save group of files to one file / Group by” option in the Multipage settings.

Orientation choice: Vertical stacking is best for documents/slides; horizontal stacking is useful for panoramas or side-by-side comparisons.

Supported Inputs and Outputs

reaConverter supports a wide range of input formats, including:

• PDF – Portable Document Format
• TIFF – Multipage Tagged Image File Format
• TGA (Targa) – High-quality graphics with alpha channels, common in animation
• CGM (Computer Graphics Metafile) – Vector format for precise technical diagrams
• CG4 (CALS Group 4) – Compressed raster format for engineering documents
• PLT (HPGL Plotter) – Vector-based format for CAD and plotting applications
• And many other raster and vector formats

Output formats include formats that don’t natively support multiple pages:

• Single-page outputs: JPG, PNG, BMP, …
• Multi-page capable: TIFF, PDF

When converting to single-page formats, Merge to One Image ensures no content is lost by combining everything into one continuous image.

Command line and Automation

You can automate Merge to One Image jobs with reaConverter’s command line and Watch Folders to integrate this into production pipelines or hands-off workflows (useful for scheduled exports or large batches).

See the automation and integration section in the reaConverter tutorials for parameters to enable multipage merging and choose orientation.

Practical Use Cases

Marketing: Export an entire product catalog as one scrollable JPG image for Instagram stories or website previews.

Education: Merge lecture slides into a single PNG reference image for students.

Technical documentation: Combine multi-page technical drawings or scanner outputs into a single image for quick review.

Web graphics: Convert multipage PDFs to single PNG images for easy embedding in web pages without viewer plugins.

Tips & Troubleshooting

Large final files: A long merged image can become very large. If file size is an issue, lower output DPI or use JPG compression.

Different page sizes: If source pages vary in width/height, consider normalizing size (resize pages or set a fixed DPI) before merging to avoid unexpected padding or misalignment.

Order of pages: Make sure input files/pages are in the correct order in the file list before converting, the merge respects that order.

Preview first: Always preview one example output when changing orientation or quality settings to confirm the result.

Example: convert a PDF booklet to one long JPG

• Add booklet.pdf
• Saving Settings → Multipage files → “Save all processed files to one file” → check “Merge to one image” → choose Vertically
• Output format: JPG, quality 85%, DPI 150
• Click Convert
• Result: booklet_merged.jpg (single long image)

Conclusion

The Merge to One Image feature is a simple but powerful tool for turning multipage content into single, shareable images — especially useful when working with formats like JPG, PNG, or BMP that don’t support multiple pages. It’s great for presentations, social media, documentation and faster review. The feature works offline, integrates with reaConverter’s batch and automation tools for production use, and ensures no content is lost when converting from multipage to single-page formats. Try different orientations and output settings on a sample file to find the balance of quality and file size that fits your workflow.

Managing large numbers of files can be a daunting task, especially when generic filenames like “IMG_0001.jpg” make it hard to find what you need. By using metadata, hidden information embedded in files, you can automate file renaming to improve organization and search engine optimization (SEO). In this guide, we’ll show you how to use reaConverter to batch rename files with metadata like EXIF, IPTC, and XMP.

Install reaConverter

What is Metadata?

Metadata is data about data, stored within files to provide useful details. Here’s a quick breakdown of the main types:

• EXIF (Exchangeable Image File Format): Captures technical info like the date a photo was taken, camera settings, and GPS coordinates.
• IPTC (International Press Telecommunications Council): Includes descriptive details such as titles, keywords, captions, and copyright notices.
• XMP (Extensible Metadata Platform): A flexible standard for additional metadata, often used with raw images or other file types.
• DICOM (Digital Imaging and Communications in Medicine): Medical imaging standard that embeds patient information and imaging parameters directly into medical image files. Key tags include patient name, birth date, acquisition date and time, study description, modality (CT, MRI, X-ray, etc.), institution name, and technical imaging parameters. DICOM metadata ensures proper patient identification and enables integration with hospital information systems.

Metadata helps protect copyright, manage digital assets, and make files more searchable – perfect for photographers, e-commerce managers, healthcare professionals and content teams.

Why Use Metadata for File Naming?

Renaming files with metadata offers two key benefits:

• Boost SEO: Descriptive filenames like “red-shirt-model123.jpg” help search engines understand your content, improving visibility in image searches.
• Stay Organized: Automatically adding details like dates, keywords, or project codes keeps your files structured and easy to locate.
• Ensure Medical Compliance: In healthcare, incorporating DICOM metadata into filenames (like patient ID, study date, and modality) creates standardized naming conventions that support regulatory compliance, prevent patient misidentification, and enable seamless integration with medical databases and PACS systems.

Step-by-Step: Batch Rename Files with reaConverter

reaConverter simplifies the process of renaming files using metadata. Follow these steps:

1. Select Your Files

Open reaConverter and load the files you want to rename. It supports over 700 file types, including images (JPEG, TIFF, RAW, DICOM), documents (PDF, Office files), and even CAD or GIS formats.

2. Create a Naming Template

Go to the renaming options and define a template using metadata placeholders. For example, “<XMP_DESCRIPTION>_<EXIF_DATE_TIME>.jpg” combines keywords and the photo’s date. Use macros to pull specific metadata into filenames, mix and match these as needed.

3. Edit Metadata (Optional)

If your files need updated metadata, use reaConverter’s batch editing tool to adjust EXIF, IPTC, or XMP tags before renaming. This ensures accuracy in your filenames.

4. Run the Process

Hit Convert, and reaConverter will rename all files based on your template, convert them to your chosen format, and save them to your selected output folder.

Real-World Example

A photographer returns from a client shoot with files named “DSC_4521.jpg” that contain IPTC keywords “wedding” and “ceremony” plus an EXIF date of “2024-03-15”. Using the template “(IPTC.Keywords)_(EXIF.Date).jpg”, the file becomes “wedding_ceremony_2024-03-15.jpg” – immediately more organized and searchable.

In a medical imaging department, a radiologist receives CT scan files like “SCAN001.dcm” that contain DICOM data including patient ID “P12345”, acquisition date and time “20240715_143022”, and modality “CT”. Using the template “(PatientID)(AcquisitionDateTime)(Modality).dcm”, the file becomes “P12345_20240715_143022_CT.dcm”, ensuring proper patient identification and streamlined integration with the hospital’s imaging system.

Supported File Formats

reaConverter works with an extensive range of file types to accommodate different professional workflows:

• Images: JPEG, TIFF, PNG, RAW, PSD, BMP, and dozens more
• Documents: PDF, Word, RTF, XPS, and other office formats
• Specialized formats: CAD files (DWG), GIS imagery (KML), medical imaging (DICOM), and many others

This broad format support means you can standardize your file naming across different departments and file types using a single tool.

Best Practices and Tips

• Choose Relevant Keywords: Use specific terms (e.g., “blue-widget” instead of “image”) for better SEO and clarity.
• Keep Folder Structure: reaConverter can preserve your subfolders during renaming.
• Backup Originals: By default, source files stay untouched – perfect for safety.
• Automate with Watch Folders: Set up a folder to auto-rename new files as they arrive.
• Combine Tasks: Rename while resizing, watermarking, or converting formats in one batch.

Conclusion

Batch renaming with metadata using reaConverter streamlines file management by automating the process and ensuring consistent naming conventions. This approach works well for organizing product images, corporate assets, or medical imaging files where metadata can help maintain proper patient identification and study organization. The automated process reduces manual errors and creates more searchable, systematically organized file structures.

Convert CorelDRAW CDR files to press-ready CMYK PDFs in seconds, no CorelDRAW required. Step-by-step GUI, CLI, and Watch-Folder workflows in reaConverter 8.

Need your CDR artwork in CMYK-ready PDF but can’t find the switch?

reaConverter hides the option in the format-specific dialog — one click unlocks a print-perfect, press-ready file. The guide below shows exactly where that setting lives, why CMYK matters, and how to batch or automate the workflow.

Why CMYK?

Printers use Cyan-Magenta-Yellow-Black inks, so delivering PDFs in CMYK avoids on-press colour shifts that can happen if an RGB file is auto-converted downstream. CorelDRAW users often export pre-separated PDFs inside Corel, but if you don’t own the software, reaConverter lets you do the same conversion offline and in bulk.

RGB vs CMYK difference:

• RGB (Red, Green, Blue) – Used for screens and digital display
• CMYK (Cyan, Magenta, Yellow, Black) – Used for commercial printing

Why convert to CMYK:

• Print accuracy – Colors will match your printer’s output capabilities
• Professional requirements – Print shops often require CMYK PDFs
• Color gamut control – Prevents unprintable RGB colors from causing issues
• Prepress standards – Meets industry requirements for commercial printing

Step-by-Step: Converting CDR to CMYK PDF

1. Add your .cdr file(s) in reaConverter.
2. In the bottom bar choose Save as PDF.
3. Click the gear icon next to PDF to open Saving settings – PDF.
4. Under PDF settings tick Save PDF file in CMYK color space.
5. Hit Apply Convert. Your new PDF is now device-independent and press-ready.

Troubleshooting CMYK Conversion Issues

Problem: Colors look different after CMYK conversion

• Solution: This is normal – CMYK has a smaller color gamut than RGB
• Tip: Preview colors in CMYK mode in CorelDRAW before converting

Problem: File size becomes too large

• Solution: Adjust compression settings or reduce quality to 85%
• Alternative: Use “Balanced compression” instead of “Optimal”

Problem: Black text appears as composite black

• Solution: Enable “Convert text to curves” to ensure proper black
• Alternative: Check original CDR file uses 100% black (K) only

Problem: Can’t find CMYK setting

• Solution: Make sure you’re clicking the settings gear icon next to PDF format
• Location: Look in “PDF (raster) settings” section, not security settings

1. What’s HEIC & Why Convert?

HEIC (High-Efficiency Image Container) is Apple’s modern photo format — great for iPhone storage, not so great for Windows workflows. Some apps refuse to open it; others strip metadata or struggle to export.

Converting to JPEG solves:

• Universal compatibility (opens on any OS, browser, or CMS)
• Easier editing in Photoshop, Lightroom, Paint.NET, etc.
• Simpler printing — many labs & kiosks reject HEIC outright

Batch conversion saves time and keeps EXIF data intact if done right — exactly what this guide will show.
