I don't think I've ever had a problem with this before, but I can not get any Sketchup components to cut an opening in a wall. I started out building my own simple windows and trying to get them to cut into a wall with thickness. That wouldn't work with components within components, changing the cutting plane around or anything.

So I tried just drawing a rectangle, making a simple rectangle cutting component, and even that won't cut. I have the fill on the component deleted, I have the right boxes checked. Any advise from the SU gurus?

Thanks,
Brad
