Question:
Can nTopology export STEP files? Can users export to CAD? What file types can I import?
Answer:

Point Data
Voxel Grid
Slices
CAD Geometry
Parasolid formats tend to yield the most dependable results. CAD and STEP inputs of single-part or multi-body files are also typically robust. For assembly files, we suggest exporting to Parasolid with a flat assembly hierarchy.
