3D Workflow

From 3D model to picture

Product pages, manuals and reports need pictures, not SIB files. reaConverter renders each model to APNG at the angle you set, a whole folder at a time.

  • Set the camera angle on X, Y and Z, or start from the isometric preset
  • Draw isometric, top, front or side views as line drawings with 2D projection
  • Pick up new models automatically with Watch Folders
  • Render a turning model as an animated GIF when one still image is not enough
