I have a set of medium-sized parts (each roughly 10–50 cm) that currently exist only as triangulated STL meshes. They need to be machined on a CNC lathe for a series of custom projects, so I must receive a single, watertight STEP file for each part—free of faceting, noise, or broken edges. Automatic mesh-to-BREP tools have already proven inadequate; the geometry has to be redrawn with smooth, continuous NURBS surfaces suitable for precise turning operations. Dimensional fidelity to the original STL is important, but the surface finish takes priority: basic, perfectly smooth contours without unnecessary micro-facets or decorative detail are all that’s required. I will supply: • The original STL files • Reference dimensions where critical You will: • Rebuild the parts from scratch when necessary, rather than relying on direct conversion • Produce clean, overlap-free solids that import into Fusion 360 / SolidWorks without errors • Return a separate STEP (or STP) file for each part, ready for immediate CAM tool-path creation on a lathe Acceptance criteria (reviewed on delivery): 1. Opens in Fusion 360 with no healing prompts 2. Surfaces show as analytic (cylinders, planes, etc.)—no mesh bodies remain 3. Key dimensions match the STL within ±0.05 mm 4. File is a single closed solid body If this is within your wheelhouse, let’s get started—I can send the first STL right away.

Dear Client. Hire ME! I understand that automatic mesh-to-BREP conversions often fail for precision machining, so I’m prepared to redraw geometry from scratch where needed to ensure smooth analytic surfaces and perfect solids. My workflow focuses on accurate surface reconstruction—using cylinders, cones, planes, and smooth lofts—so the final STEP files import into Fusion 360 or SolidWorks without healing prompts. I’ll match your critical dimensions within ±0.05 mm and deliver a single closed solid body per part. If you send the first STL, I can start immediately and provide the STEP files ready for CAM.
