Graphical Editing of Roof Geometry

To graphically edit the geometry of a selected Roof, edit any of the following:

the pivot line

a ridge line

the Roof level dividing line, if your Roof has several levels

the Contour line

To edit the pivot line, use the familiar polygon editing commands in the pet palette:

As you can see in 3D, editing the pivot line adjusts the geometry of the roof plane and of the adjoining planes as needed:

Below, we have added an extrusion to the roof using the Add to Polygon editing command of the pet palette. The resulting roof geometry is modified, with each roof plane adjusted as needed, and the roof remains a coherent single element.
