I just had to improvise a bay window from the OOTB 45deg unit. Changing height param failed miserably. The csmt sides weren't constrained to the same height as the picture, nor was several other little items.
If Adesk & Revit can't get families right, wtf? Sure this fam was made years ago & probably done by some intern, but c'mon folks.
I'd really like to see someone (Jeff?) look into this & actually post a reply - or defense. Whatever. Maybe time to review ALL of the OOTB content for accuracy.
