I occasionally want to bring just a 3D model into my layout to show fit. Heat sinks for example.
In that case, there do not seem to be good options. Here is what I have done. I am asking if there is a better way.
- create footprint with one pad, associate the 3Dmodel to it. In layout this works, I can move the virtual component by grabbing it by the one pad. Down-side, I have a pad on my layout that does not belong. What I have done with heat-sinks is place that pad at the same place as a mounting hole on the layout. That creates two overlapping pads, which is okay, except I have to ignore the DRC error.
- create a footprint with NO pad, associate the 3D model. In layout, after I place it, I can’t seem to move it. There doesn’t seem to be a way to grab that part without a pad. Good news is there are no DRCs.
Any other suggestions? Goal would be to place a virtual component, and be able to move it around, without introducing any layout features that will cause fabrication or DRC issues.
