Roof Pivot Line

The roof’s elevation is measured by the elevation of the pivot line or pivot polygon, a horizontal non-printing line that you draw when creating the roof. A Roof’s pivot line or pivot polygon can be edited to graphically change Roof geometry, which is especially powerful with Multi-plane Roofs. In the 3D window, pivot lines are shown with a specific colour r to make editing easier. You can change this colour (“Reference lines in 3D”) in Options > Work Environment > Selection and Element Information. You can hide all pivot lines on the Floor Plan, by disabling the Roof Pivot Lines option in View > On-Screen View Options.
