3D Workflow

From 3D model to 2D drawing

Converting SIB 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
  • Pick up new models automatically with Watch Folders
  • Rotate the model on X, Y and Z before projecting
  • Keep unreleased designs and client models on your PC: nothing is uploaded

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!

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

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!

I'm a construction project manager, and I get DWG files from architects every week. reaConverter turns them into high‑res PDFs for my field team in seconds. No more AutoCAD licenses needed for everyone – just a simple converter that works. Total game‑changer.

The program's interface is refreshingly simple and intuitive. The entire process is streamlined to just a few steps: specify your source files, set an output folder, and you're done! Batch processing works flawlessly too. An excellent tool that makes file conversion effortless.

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.
