After creating a roof, you can change its shape or overhang, cut openings, or align ridges.
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 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.

You can align roof ridges in 3D and elevation views. To align roof ridges in an elevation view, use the Align tool.

If a roof includes a slope-defining arc line or circle, it creates a conical roof. If desired, you can divide the arc or circle into segments as follows.
If you specify zero segments (the default), a conical roof is created.
