The library object Cabinet Base 1D 12 which appears to have been updated in the latest library patch, LIB12-USA-2528-Win.exe, is exhibiting strange behavior. (Similar issues occur with Cabinet Base 2D 12 and Cabinet Base 3D 12 as well)
To recreate/illustrate the oddity, test the following settings:
Size to Set - Cabinet
Sink - None
The cabinet depth cannot be set to be less than 2'-3". In the previous library, I could create base cabinets to a shallower depth.
Furthermore, the cabinet will incrementally grow by 3" each time the Mirror Library Part box is checked/unchecked. It seems that the incremental growth only occurs when the Size to Set box is set to cabinet. If one of the sink options are set to either Style 1 or Style 2, the cabinet depth can be adjusted down to 1'-3 3/4" or 1'-9 21/32" respectively.
The intention is to be able to create a 9" or 12" deep base cabinet, which was possible until the latest library update.
By the way, if the sink is turned off on Cabinet 2D and Cabinet 3D, the cabinet depth can be reduced to 12". (Even 6" is possible.)
