Unfortunately even if i try to talk in english you won’t understand anything
Archipack roof is able to fit a roof into another one for you.
Take a look at
Create your main roof, then create another one (the smallest cutting one)
In the smallest “child” roof, select the main one in the “Parent” field, you’ll then be able to select the part # of main roof you want this one to be (if you have a multi part main roof) and Dist x and y to locate your child roof on the parent.
Hole parameters allow to modify hole shape done on parent.
You also are able to set the angle of the child wall using first part start angle parameter, where -90 will change the side of the child left instead of right of parent axis.
