• Use names that are 32 characters or fewer. You can use alphanumeric characters and underbars. Names must start with alphabetic characters.

• The software does not permit you to use a name already used for another load, constraint, or boundary condition.

• Use names that uniquely and clearly identify the objective, placement, or other key characteristic of the set. If you use the default names, you or other users may have trouble distinguishing the sets later.

• You can include as many different types of constraints as you want within a single constraint set.

• There is no limit to the number of constraint sets you can create or the number of constraints you can include in a constraint set.

• You can edit and delete the individual constraints that make up a set. You can also edit and delete a constraint set. With constraint sets, you can change the set description or the name.

• You can remove a given constraint from its set by editing the constraint and changing the selected set. Use the name of a set that already exists, or click New. The software adds the constraint to that set.
