Technical note

STL to DWG: what carries over and what does not

Converting STL 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

Converting STL to DWG usually means getting flat views out of a 3D model. reaConverter generates them in batch, with no CAD seat on either side.

  • Choose an isometric, top, front or side 2D projection, with hidden edges dashed or removed
  • Rotate the model on X, Y and Z before projecting
  • Keep unreleased designs and client models on your PC: nothing is uploaded
  • Script the job from the command line for pipelines and scheduled runs

I typically avoid installing too many programs to keep my hard drive clutter-free, but constantly uploading/downloading files for conversion became too time-consuming. That's why I chose reaConverter when I needed to transform DWG files into readable PDFs—and it performs flawlessly!

After nearly two years of relying on online converters, I finally installed standalone software. Why didn't I do this sooner? Now I can work completely offline — no more wasted time uploading/downloading or eating through my data allowance!

When uni gives you DWG files but you're not an CAD expert yet... 🥴 Thank goodness for reaConverter! First try success → now studying these blueprints on my iPad. Lifesaver for freshman year! #EngineeringStudent

If you work with AutoCAD, Autodesk, or similar CAD software, you’ve likely faced format compatibility issues. Every developer seems to insist on their own proprietary formats, making conversions a real challenge. The solution? reaConverter. This tool effortlessly handles two-way conversion between dozens of specialized formats!
