Exports

STEP keeps the exact solids, for CAD and machining. STL and 3MF are meshes, for printing.

Option Choices
Format STEP, STL or 3MF
Parts Every part, or the ones you choose
Files One combined file, or one file per part
Positions, for one file per part As assembled, or each part at the origin
Mesh, for STL and 3MF Coarse, normal or fine

Exports carry geometry and part names only, with the same options on every plan.
