3D Workflow

From 3D model to picture

Product pages, manuals and reports need pictures, not STP files. reaConverter renders each model to QRT 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

reaConverter handles STP file conversion excellently. The batch processing feature is perfect for converting multiple CAD files at once, and the drag-and-drop interface makes it super easy to use.

I firmly believe working with JPEG — the universal format supported by all devices and apps—is the wisest choice. reaConverter handles these conversions flawlessly.
