Maurice,
You are correct. Launching from the command line fixes the WRL display issue.
I have StepUp working now on a new board design and updated a previous design. The workflow is straight forward after walking it once. Currently, I am exporting boards into Inventor as part of a larger product assembly. The previous workflow was to export the IDF, then populate the major component STEP models on the MCAD side.
This works great, thanks for all your effort on this. Between this effort and CERN’s differential routing features, I have been able to move to KiCAD instead of a much more expensive option.
