After completing a roof, you can modify its physical structure, change its properties, or join it with another roof.
If you want to change the position of the roof, use the Properties palette to edit the Base Level and Offset properties to change the position of the reference plane. If you’re warned that the roof geometry cannot move, edit the roof sketch, and check for constraints on the sketch, such as between a level line and a sketch line of the roof.
Use one of the following methods to change the roof type:
In sketch mode
In a project view
Use this method to resize roofs that were created by footprint or by face.
When editing the footprint of a roof, modify properties of its boundary lines to change the roof overhang.
A plan view representation of the roof displays. Reference planes define the boundary of the roof.
Closed-loop sketches in sketch mode
Closed-loop sketches become vertical cuts in the roof
You can align roof ridges in 3D and elevation views. To align roof ridges in an elevation view, use the Align tool.
