If the surface is parallel to the construction plane with surface normals facing in
the same direction as the current UCS, the draft angle is 90.0. When perpendicular, it is
۰. If the surface is parallel to the current UCS with surface normals facing in the opposite direction than the current UCS, the draft angle is -90.0.

To change the draft analysis display settings, use the Draft Angle tab of the Analysis
Options dialog box.
