For a Dremel vise or precisely dimensioned part, decide before scanning whether you need a mesh reference or a true B-rep solid. Onshape’s import documentation explains supported CAD and mesh formats, and its native workspace gives you a place to test an existing SLDPRT model.
Why it matters: This is a concrete choice or experiment for today or this week.
Practical next move: Use Onshape’s supported-file list to decide what to import, then verify the result is an editable part rather than only a triangulated mesh.

An STL mesh and an editable solid are not interchangeable. Action: Use Onshape’s supported-file list to decide what to import, then verify the result is an editable part rather than only a triangulated mesh.
