Technical note

Before you convert IGS to DWG

Converting IGS to DWG can produce two different files. With Create 2D projection switched off, the DWG receives the model itself as 3D geometry, which a CAD program can orbit and view from any side. With it switched on in the 3D formats loading settings, the DWG receives a flat view instead: isometric, top, front or side, with hidden edges dashed or removed. Neither version carries dimensions, a title block or section views, so treat the result as the start of a drawing rather than a finished sheet.

3D Workflow

From 3D model to 2D drawing

Need DWG views of IGS models for documentation, quoting or a laser cutter? reaConverter projects each one to a drawing, a folder at a time.

  • Choose an isometric, top, front or side 2D projection, with hidden edges dashed or removed
  • Script the job from the command line for pipelines and scheduled runs
  • Use the top view as a cutting profile for lasers, waterjets and CNC routers
  • Pick up new models automatically with Watch Folders

The proliferation of niche formats like DWG creates unnecessary hurdles. After wasted hours on forums, I discovered this lean converter that delivers single-purpose excellence—precisely the 'no nonsense' solution CAD beginners require.

I inherited a mess of DWG files from a previous engineer – all in different versions. reaConverter batch‑converted them all to a single, clean DWG format (2018) with no errors. It even fixed some corrupt headers. This tool is a miracle worker.
