Through hole components holes do not get exported into step files PCB assembly (PADS 3D export).
Mounting holes do show up in model
Is there a fix for this?
From what I have found there is no way to get a non-plated mounting hole to show up in the 3D model. You can however get a plated through hole to show up in the 3D model if you add an attribute called "hole" to the part type. At least that has worked for me an it is also the way to get the holes to show up in an IDF file as well.
Make part an non-eco part. See thread here: 3D PCB
