This task shows how to set geometric constraints on geometric elements.
Such a constraint forces a limitation. For example, a geometric constraint might require that two lines be parallel.
Multi-select two or three elements to be constrained.
Click Constraint defined in dialog box .
Select one of the available options to specify that the corresponding constraint should be made.
Click OK.
Select the element to be constrained.
Click Constraint .
The corresponding constraint symbol appears on the geometry.
