Technical note

What changes when you convert OFF to STEP

OFF stores a surface made of triangles, while STEP is built for exact solid geometry. The conversion has to derive surfaces from that triangle mesh, so the result is faithful to the shape but is not the same thing as a parametric model with clean features and editable dimensions. OFF holds bare numbers with no unit, and STEP has to state one, so the conversion has to assume it. If the OFF was exported in inches or metres, the result is off by that same factor. Measure one known dimension after conversion.
