Setting A Perpendicular Lift As The Working Surface
Some special applications require a specified thickness of material to be laid over a Design Surface. Using perpendicular lifts, the thickness of material is the same on slopes and level sections of a design. Illustration 23 is a Cross Section view showing a perpendicular lift applied to a design.

In order to change the Perpendicular Lift value, do one of the following:
Use the arrow keys
Press "+0.50" in order to add that amount to the current value
Press "-0.50" in order to subtract that amount from the current value
