One more problem about roofs

Daniel_He

Hi I was creating a roof using multiplan complex roof method, one problem is in the red area showed in picture 1 and 2, the room wall is 2 feet lower than the other rooms, so I want to drop down this area root 2 feet, but I couldn't find the way if I draw the roof as an unique part. So I tried to seperate roof to 2 parts and set lower area to project zero 2 feet lower, but the valley of roofs are not acceptable as showed in picture 3 blue mark. So what is the best solution to solve this problem, thanks.

One way that I use for this type of situation is to move the pivot line inward on all sides. You will need to calculate the amount to move by using the pitch ratio x (the width of the room divided by 2) i.e. 5/12 x (14'\2)=2.91 feet

You can select each edge around where the two roofs intersect and set a custom offset for them.
