Technical note

What changes when you convert STP to DWG

Converting STP 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. Without further settings, a STEP assembly converts to a single DWG. With Load STEP as separated shapes switched on, each part becomes its own file instead, so one assembly fills a folder with one DWG per part.

3D Workflow

From 3D model to 2D drawing

Converting STP 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
  • Script the job from the command line for pipelines and scheduled runs
  • Use the top view as a cutting profile for lasers, waterjets and CNC routers
  • Pick up new models automatically with Watch Folders
