DWG solid conversion
Jens Fursund, May 20, 2026DWG files with ACIS solids now have a real 3D conversion path.
If you've used other converters, you may have found yourself with an empty file after converting an Autodesk DWG.
That usually points to ACIS solids inside the file.
Convert3D now extracts those solids, writes them through a STEP path, and lets Open CASCADE do the kind of CAD healing that makes fillets, pcurves, orientation, and closed surfaces survive the trip.
How to use this right now
Drop in a DWG with 3D solids and convert it to GLB, STEP, or another supported format.
