DWG is a proprietary format of AutoCAD — probably the most popular software for drafting 2D and 3D models in the construction industry. Widely used by engineers, architects, designers and other professionals in this branch, the DWG extension is also compatible with several other computer-aided design programs, including IntelliCAD or Caddie.
Most CAD programs offer users 2 types of drafting environments. One is “model space”, where a draft model is initially sketched according to a defined representation scale, and the other is “paper space”, to which users can switch to when preparing a model for printing. The latter allows you to create several layouts, offering different views of the model. Multipage DWG files can contain both “model” pages and “paper” pages.
