Since AC11 the wall trimming feature is not working properly. Not sure if this is only related to my system? After trimming multiple walls to a roof at once, some walls are completely disappearing? Trim must be undone to get them back. The only way to avoid it is to drag wall and roof individually away from model and perform the trim one at a time.
I have also noticed walls being trimmed to roofs with no trim having been performed?
Maybe I have a split personality?
Any help would be great.
If I have that issue, instead of dragging the elements away from the rest of the model, I select the items I want to trim, jump into 3d, trim them, then jump back.
