Convert Character STL to STP

I have a small batch of 3D character models—no more than five STL files—that I need precisely converted to STP format. The meshes are already finalized, so the job is a straight-through conversion: no scaling, reshaping, or other edits.

You’re free to use whichever CAD tool you trust most—SolidWorks, Fusion 360, FreeCAD, or similar—as long as the resulting STP files open cleanly, preserve all surface details, and remain watertight.

Deliverable
• One STP file for each original STL, ready for immediate import into parametric CAD environments.

I’ll share the STLs as soon as we start and will confirm successful conversion by opening each file on my end. A quick turnaround is appreciated, and I’m happy to answer any questions before you begin.
