Intersecting Roof PLanes

Hi, I’m using the roof by Tig extension, and it works great at times, however I find that when intersecting roofs it creates a heck of a mess inside the roof geometry. This is fine if you’re just doing elevation views, but if I cut a section it’s messy. If I want to include a vaulted ceiling it’s messy.

If I edit the group and try to erase back to the intersecting plane it deletes half of the roof. Intersect faces with model does nothing.

Make sure all of the roof sections are in the same group, select all of the geometry, right click on it, choose Intersect Faces>With Selection. Then erase what you don’t want.
