Technical note

STP to GLB: what carries over and what does not

STP 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

Most printers, slicers and web viewers cannot read STP. reaConverter turns the parts into GLB meshes in batch, without a SolidWorks or Fusion seat.

  • Set the level of detail from 1 to 7: finer triangles for smooth curves, fewer for small files
  • Split an assembly with Load STEP as separated shapes, one GLB file per part
  • Pick up new models automatically with Watch Folders
