To test-fit a part into a mechanical design, the 3D export model needs to be precise. Right now the thickness of the PCB cannot be specified when exporting the 3D model, and as such test-fitting the pcb in a mechanical CAD program for a given enclosure becomes problematic. It would be very helpful if board thickness was parameterized in the export process.
