Working with Parameters

You can create parameters and assign values to these parameters.

Parameters are features that can be constrained by relations and that can be used as the arguments of a relation.

This task shows you how to:

Create a Parameter

    The Parameter panel appears.
  2. From the Parameter Type list, select one of the following types:
    • Length
    • Angle
    • Area

    • Real
    • Integer
    • Boolean

    This option is not available when you create a Boolean parameter.
  6. Validate .

    Tip: To create several parameters in a row, you can click Apply, define another parameter in the panel, and then validate.

    • Click Create Parameter from the Tools section.
