The color spectrum shows draft angle changes within a specified range. The maximum draft angle displays as red, and the minimum draft angle displays as blue.
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 0. 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.
