3D Workflow

From picture to 3D model

Need a 3D STP from a flat QOI image? reaConverter vectorizes it, extrudes the shapes to the height you set, and works through a whole folder at once.

  • Each image is vectorized first, then extruded to the height you set in millimetres
  • Works best with logos, signs and line art: a photo has no clean outlines to follow
  • Apply the same height and tracing settings to every image in the batch

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. Quality is preserved well during conversion, and it supports plenty of output formats. Recommended for engineers and designers.

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