Convert STL Files to Clean CAD / STEP Models I have a number of STL files that need to be converted/rebuilt into proper CAD models. The STL files are the only source files available, so this will require reverse engineering of the STL mesh into clean CAD geometry. Required Deliverables * Clean STEP (.step / .stp) file for each STL supplied * Proper solid CAD geometry — not simply the STL triangles converted into STEP faces * Smooth curved/cylindrical surfaces where applicable * Holes, radii, fillets and other features recreated accurately * Models should be suitable for: * CNC machining * Further CAD modification * Scaling/resizing * Manufacturing Where practical, I would also like the editable native CAD file (SolidWorks, Fusion 360, Inventor, etc.). Important Please do not bid if your process is simply Mesh → BRep → STEP, leaving thousands of triangular faces. I am looking for someone experienced in reverse engineering STL/mesh models into clean CAD solids/surfaces. The original STL geometry and dimensions should be maintained as accurately as possible. When bidding, please tell me: 1. Which CAD software you will use. 2. Whether the final STEP files will contain clean reconstructed surfaces. 3. Whether you can provide the editable/native CAD files as well. 4. Your price per model or price for the complete batch. 5. Estimated turnaround time. I can provide the STL files for review before the final price is agreed.

Hello, We can reverse-engineer your STL meshes into clean, editable CAD solids rather than simply converting mesh triangles into STEP faces. Our workflow focuses on rebuilding recognizable geometry, smooth surfaces, holes, fillets, radii, and cylindrical features accurately for manufacturing and future modification. We primarily work with SolidWorks and Fusion 360, enabling We to provide clean reconstructed STEP files along with native CAD files where required. We will carefully maintain the original STL dimensions and geometry while creating a logical, editable feature structure. We can review the STL batch first and then provide an accurate per-model or complete-project quotation and turnaround based on complexity. Thanks

Hello, Your STL files need true reverse engineering into clean, manufacturable CAD solids, not faceted mesh conversions. I can rebuild each model from the STL reference in SolidWorks / Fusion 360 / Inventor, recreating cylindrical faces, fillets, holes, and radii so the result is suitable for CNC, scaling, and further edits. I’ll first inspect each mesh, identify the key geometry, then reconstruct accurate solid/surface features and validate dimensions against the original STL. You’ll receive clean STEP files and, where useful, the editable native CAD files as well. Which CAD platform do you prefer for the native files, if you’d like them included?

Hi there, I’m Mohand, a Mechanical Engineer experienced in SolidWorks, CAD modeling, reverse engineering, and manufacturing-ready product design. I can rebuild your STL meshes into clean parametric CAD solids, rather than simply converting mesh triangles into BRep geometry. Scope of Work: ☑ Reverse-engineer each STL to recreate accurate planes, cylinders, curves, holes, fillets, radii, and other functional features. ☑ Validate dimensions and geometry while maintaining the original design intent and ensuring the models are suitable for CNC machining, scaling, and future modifications. ☑ Deliver clean STEP/STP files plus editable native SolidWorks/Fusion 360 files where required, with a final geometry and manufacturability check. My preferred workflow is SolidWorks, using surface reconstruction and parametric feature modeling where appropriate to produce clean, editable geometry. Please send a few representative STL files so I can review their complexity and provide an accurate per-model or batch price and turnaround time. Best Regards, Mohand

Hi! This is directly aligned with my reverse engineering work. I use Fusion 360 to rebuild STL meshes into proper parametric CAD geometry rather than simply converting the mesh to BRep. I will reconstruct the main features, holes, fillets, cylindrical and curved surfaces as clean geometry while keeping the original dimensions as close as possible. The final deliverables can include clean STEP files plus the editable Fusion 360 source files. I also have a relevant mesh-to-solid conversion project in my portfolio that shows this type of workflow. Since the number and complexity of the STL files can significantly affect the workload, I’d prefer to review the files first and then confirm the final batch price and turnaround time.
