I use Smart Parts, have for years. I started back when Ac wouldn't even give you control of the trim. SO, I am not really that familiar with AC's windows and doors. I did change over to AC's cabinets. I like them, and never upgraded SmartPart's version.. so I can't say much comparing them either. I use a few of the Trim library, but not much. He has a nice trim that you can set at a slope, which I use for rake trim.
I'll attach a schedule I generate so you can see the results. It does list ganged as one unit. I manually fill in the "single" or "twin" note. Same with the doors, I fill in the interior and exterior. Those fields are actually the ID field.
