I have four finished 3D models in .STL format that I need translated directly into .STEP, strictly one-to-one—no editing, healing, or redesign. Each source file is under 200 MB, which is the upper limit my CNC workflow can accept, so the resulting .STEP files must stay within that size range as well. These parts are for a prototyping run on a milling machine, so dimensional fidelity is critical. Deliverables • 4 .STEP files converted from the supplied .STL models • A simple verification sheet or screenshots confirming dimensions and details match the originals That’s the whole scope—clean, accurate, ready-to-mill files and a quick confirmation they’re identical to the inputs.

Thanks for sharing the details clearly — I understand the importance of maintaining exact geometry for CNC prototyping. I can convert your four .STL files into .STEP format with a strict one-to-one approach, ensuring no redesign or unintended dimensional changes. That said, I want to be transparent about one technical point: STL files are mesh-based (triangulated surfaces), while STEP files are solid/parametric formats. A direct conversion without any form of surface reconstruction typically results in a “faceted” STEP model rather than a true analytic solid.
