Adding opng in Hollow Core Plank

[MXM]

I noticed a past post in regards to adding an opening in a Hollow Core Plank family. I thought, hmm, I could use one of those. After placing the void extrusion in the appropriate family, I was able to get the opening to flex in the long direction. However, I'm runnning into difficulty getting it to flex in the width direction. Any ideas? I'll attach what I've done so far.

If you go to the Autodesk website and download the UK library, you'll find families ready for use in RST2009.

As for adding voids, the best strategy is to create a face-based family and do you void there. Then nest that family in the second family and place the face based family on your solid. Connect the appropriate parameters and array the face based family. Or just download the above mentioned family :)
