How It Works

Technical note

What changes when you convert STP to WEBP

A 3D model has no front of its own, so the WEBP shows it from one viewpoint: the angles you set on the X, Y and Z axes, or a preset such as the isometric view. Whatever faces away from that viewpoint is not in the picture, so a part with features on several sides needs several images, which the multiple-frames option renders in one run. Without further settings, a STEP assembly converts to a single WEBP. With Load STEP as separated shapes switched on, each part becomes its own file instead, so one assembly fills a folder with one WEBP per part.

3D Workflow

From 3D model to picture

Product pages, manuals and reports need pictures, not STP files. reaConverter renders each model to WEBP 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
  • Pick up new models automatically with Watch Folders
  • Render a turning model as an animated GIF when one still image is not enough
  • Keep unreleased designs and client models on your PC: nothing is uploaded
