I am trying to use the 3D step package mapping capability in Allegro (16.6 S038), but find that many step files don't work. I am downloading step files from 3dcontentcentral.com. I find some work just fine, but others do not show up in the mapping window preview or when in the 3D rendering of the PCB. I am pretty sure there is nothing wrong with the step files because I am able to load and view them fine in Solidworks.
Is anyone else experiencing this problem or have any suggestions/workarounds?
Thanks
