Technical note

What changes when you convert STP to IGES

Without further settings, a STEP assembly converts to a single IGES. With Load STEP as separated shapes switched on, each part becomes its own file instead, so one assembly fills a folder with one IGES per part.

reaConverter converts STP models to IGES on your own PC, a folder at a time, with nothing uploaded.
