Trimming Walls to Roof and Slabs, and Trimming Roof

I can’t figure out how to trim the red areas away from the below to get only the blue elements. I get the green element, and can’t get rid of the peak of the roof.


use the Extend command (_vaWallExtend in the command line)



Thanks, but that gives me the green triangle. I need to extend/trim it to both the roof and the slab.

I can’t get rid of that green triangle (which is created by extending to the roof) by trimming to the slab. Nothing happens. Had to make in a shed roof of 0 slope and trim to that, which worked. Is there a way to extend to slabs?


You can use a boolean operation

or split the wall in 3 parts
