Are there any tricks for trimming walls to roofs, where there are more than one object on the roof layer.
For example I have a roof that I want wanting to extend my walls to. However there are also old roof objects which are classed as removed.
There are also beams etc that get in the way.
I had hoped that by turning these other classes off that the walls would trim to the visible roof.
I know I can create new layers and then move the roof there, trim and then move back.
Seems like a roundabout way to achieve something simple.
