I have seven scanned parts in both OBJ and STL format that now need to become clean, fully editable STEP models. The files will go straight to 3D printing once finished, so surface quality and dimensional faithfulness are critical. Your task is true reverse engineering, not an automatic mesh-to-solid export. Please bring each component into SolidWorks, Fusion 360, Rhino, or any comparable professional CAD tool, rebuild the geometry so it is smooth and manufacturable, and be sure mating faces keep their original relationships—the printed parts must assemble perfectly. Key points to keep in mind • Remove scan noise while preserving design intent and overall accuracy • Maintain continuous, watertight surfaces with tidy topology (no stray triangles or self-intersections) • Verify alignment between components so fit is trouble-free after printing Deliverables • STEP file for each of the 7 parts • (Optional) native CAD files if you create them in SolidWorks, Fusion 360, etc., so I can make later edits If you have a proven mesh-to-CAD workflow, especially for parts destined for additive manufacturing, I’d love to see an example. Let me know your anticipated turnaround time and any questions about the scans, and we can get started right away.
