I have a single mechanical part saved as a STEP file and I need the entire model scaled up by a precise amount. It is not a uniform percentage change—I will supply the exact added millimetres once we start. All other geometry must remain identical; I only want the overall footprint adjusted. Please return the updated file in the same STEP format, fully intact and ready for manufacturing review. If you can turn this around quickly and double-check that all faces, holes, and references scale correctly without distortion, let’s get started right away. Dimensions Will need to be acceptable on freecad
