Constraints are applied to the 2D profile object used to create the surface, not
the surface itself. Use selection cycling to be sure that you are selecting the
profile curve and not the surface or the edge subobject. See
Apply or Remove
Geometric Constraints
on page 810.
Use Mathematical Expressions to Derive Surface Properties
Dimensional constraints are user-defined expressions that are applied in the
properties palette for that surface.
For a complete list of operators and functions allowed in expressions, see
Control Geometry with the Parameters Manager on page 842. The following
table lists the surface types and their properties that accept expressions
