Mesh to STEP is a problem a lot of people here run into, and I'd rather share real numbers than marketing claims. The problem: An STL, OBJ or 3D scan is just triangles. You can print it, but you can't properly edit, fillet, dimension or machine it in SolidWorks, Fusion 360, FreeCAD or any other CAD package. The usual options are rebuilding the part by hand, or a "convert" that wraps every triangle in a face and leaves you with a heavy, uneditable file. What MESH2STEP does: It fits NURBS surfaces over the mesh and outputs a valid, closed STEP solid, so it imports as a real solid body and not a shell of triangles. Results on the organic model in images: - Average surface deviation from the original mesh: 0.033 mm - Volume difference from the original mesh: 0.07% - 7,949 NURBS surface patches - Output: a valid closed solid (watertight), ready to edit, machine or print Where it's useful: - Scan to CAD for reverse engineering worn or discontinued parts - STL to STEP when a client or supplier only has a mesh - Organic or sculpted shapes (including AI-generated 3D models) that need to go to CNC or a CAD assembly Honest limitations: It's surface fitting, not feature recognition. You get an accurate solid, not a parametric history tree with sketches and extrudes. For prismatic parts where you need clean design intent, remodeling by hand is often still the better route. If you have a mesh that has given you trouble converting, give it a try, run it, and post the deviation numbers here.
