To create a parallel relationship between two surfaces
1 Enter dsettings and select the Selection Cycling tab.
2 Click Allow Selection Cycling to turn selection cycling on.
3 Enter geomconstraint. Enter pa to select the parallel option.
4 Select the first and second profile objects. Be careful not to select the
surface or the edge subobject.
If the surfaces were not already parallel, they are moved into a parallel location
and the parallel constraint symbol appears.
To add a user expression to specify the height of a surface
1 Right-click on a surface and select Properties.
The properties palette displays.
2 In the Geometry section, enter an expression in the Height field.
A symbol appears next to that field to indicate that a dimensional
constraint is applied to this property.
