I suspect I know the answer to this, but I'd sure like to be wrong:
Is there any way to insert a plain-old opening/cut-out in an AEC wall?
I'm modelling a window that is close to the stock hung window, but I need mullions in the upper sash and not the lower. I don't think I can create this from the variables for the AEC window. I can turn it into a mesh and do it pretty easily, but then my window opening doesn't clean up automatically. It would be oh-so-handy if I could just define an opening in the AEC wall to accompany my modelled window...is there any way to do this without doing a Boolean operation?
