Technical note

What changes when you convert U3D to DWG

Converting U3D 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 U3D 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

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!
