How to Make a Rotating GIF from a 3D Model (STEP, STL, OBJ)

by

Turn one model or a whole folder of STEP, STL and OBJ files into spinning GIF, WebP or AVIF previews, from the interface, Watch Folders or the command line, without a 3D program.

Rotating GIF from a 3D Model: STEP, STL, OBJ in Batch

Short answer: reaConverter renders a 3D model at a series of angles and saves the frames as one animated file. Open Menu → Loading settings → 3D formats, tick Create multiple frames, set 36 frames and Change Z from 0 to 360. Fix the viewing angle with Change X 75 to 75 and Change Y 5 to 5. Then save as GIF with an Animation delay time of 5. It works on one model or a whole folder, offline.

Automating File Conversion Workflows with reaConverter

by
Automating File Conversion Workflows with reaConverter

Short answer: reaConverter automates file conversion through three layers that share the same settings engine. The Windows context menu handles ad-hoc jobs, Watch Folders convert files the moment they land in a monitored directory, and the command-line tool (cons_rcp.exe) runs scheduled and scripted jobs. Watch Folders run as a Windows service and require local storage. The command line reads network paths without restriction. All three read the same .cfg configuration files and .act action files, so a workflow you design once in the interface runs identically everywhere. Watch Folders and the command line require reaConverter Pro.

This guide covers how those layers fit together, how to build a pipeline that survives unattended operation, and six complete workflows you can adapt.

How to Split Multiframe DICOM into Single-Frame DCM Files

by
Split DCM file

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.

by

Drag, drop, done — turn any folder into an instant file converter.

reaConverter’s Watch Folders

What is a “Watch Folder”?

It’s a built-in automation tool designed for non-technical users who regularly handle dozens or thousands of images, or documents.

Right-Click Conversion with Windows 11 Context Menu Integration

by

A step-by-step guide to turning reaConverter Pro into your fastest “File-Conversion-On-Demand” button.

Right-click conversion

Why bother with the context menu?

Windows 11 slimmed its right-click (context) menu and hides many third-party options behind “Show more options.” That second click slows you down — especially when you’re batching dozens of images. reaConverter Pro 8 solves the problem by wiring itself directly into the modern Windows 11 menu, so one click launches an instant conversion using your favorite preset.

If you still see the older two-step experience, Microsoft’s design simply tucks extra items under the submenu; you can always click Show more options to reveal them.

How to Rotate PLT Files During Conversion

by

If you are planning to print a graphics file on a plotting device, then converting it to PLT is the best option. Whether you are using a cutting plotter, a pen plotter or some other similar machine, the PLT format will ensure what you create on screen will match what you see in print.

PLTs are vector files that use the HPGL language and can be sent directly to print on a plotter. Such devices are often used for large-scale graphics such as maps, detailed plans or diagrams, posters and many more. The PLT format was originally created for Hewlett-Packard printers only, but in time became an actual standard in the industry. PLTs are currently compatible with most brands of plotting machines.
