Technical note

What changes when you convert STEP to GLB

STEP holds exact mathematical surfaces and GLB approximates them with triangles. Curves become faceted, and how visible that is depends on the level of detail, a value from 1 to 7 in the 3D formats loading settings. A middle value suits most printing; for a close-up render of a shiny curved part, raise it and expect a larger file. Without further settings, a STEP assembly converts to a single GLB. With Load STEP as separated shapes switched on, each part becomes its own file instead, so one assembly fills a folder with one GLB per part.

3D Workflow

From solid model to mesh

Need STEP parts on a printer, in a slicer or in a web viewer? reaConverter turns them into GLB meshes offline, a whole folder at a time.

  • Set the level of detail from 1 to 7: finer triangles for smooth curves, fewer for small files
  • Render preview images of the same models in a second run
  • Keep unreleased designs and client models on your PC: nothing is uploaded
  • Convert a whole folder of parts in one run

reaConverter has been a huge time-saver for our team. We regularly work with CAD models in STEP format, and converting them to images or other file types used to be a hassle. With reaConverter, the process is fast, accurate, and incredibly easy to set up. The batch conversion feature is especially useful when handling large projects. Highly recommended for anyone dealing with STEP files on a regular basis.
