The Match Planes tool can instantly change the plane of one roof surface to match the plane of another. This is a great tool when you have uneven plate lines but you want them to share the same roof plane to avoid a valley.
To match roof planes:
HINT: To select the roof planes it is easier to do in a 3D view or a 2D Designers view. In the 2D Plan view, the surfaces are represented by a single line that may be difficult to select but in a 3D or 2D designers view you can select the roof surface by picking in the middle of the roof.
- Click on the roof to select it, then right-click and select Match Planes. Or, select Edit > Modify Elements > Match Planes.
- Click on the roof surface whose plane you want to apply to another surface. In 3D click anywhere on the surface to select it.
- Click on the roof surface whose plane you want to match with the plane of the first surface selected. The plane adjusts.
- Right-click and select Finish.
