3D Workflow

From 3D model to 2D drawing

Converting COB 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

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.

When I switched from Mac to Windows, I couldn't open my old DWG files. reaConverter saved me – it converted them all to PDF and JPG with perfect scaling. Now I can view my CAD portfolio on any device. Thank you for making cross‑platform work possible!

My son is training to become an architect, so he's learning Autodesk, AutoCAD, and other design software. With so many file formats in this field, we needed a reliable conversion tool fast. reaConverter was the perfect solution - lightning-fast conversions, zero lag, and it works completely offline!

I needed to convert DWG to DXF for a laser cutter, and reaConverter did it flawlessly. The geometry remained intact, and the line weights were preserved. I've tried free tools, but they always mess up arcs. This is the only one I trust.
