Pro/ENGINEER Parameters

You can use Pro/ENGINEER parameters as Mechanica material properties, certain load and constraint values, design variables, or measures. This functionality enables you to do the following:

You can also use Pro/ENGINEER parameters to define the thickness of simple shells or the stiffness properties of simple springs.

Before addressing the specific issues that you need to consider when creating Pro/ENGINEER parameters for use in Mechanica, let us take a moment to review some basic concepts.

In Pro/ENGINEER, you can control many aspects of part design through the use of parameters. Parameters enable you to set particular values for a dimension, drive the value of one dimension based on the behavior of another dimension, dynamically suppress features based on changes in the part, and so forth.

You can define Pro/ENGINEER parameters in the following two ways:

Parameters created through the Relations command are sometimes known as driven—or dependent—parameters because they are controlled by the equation you define.

Parameters created through the Parameters command are sometimes known as driving—or independent—parameters because they are capable of controlling activity.

If a conflict occurs, bear in mind that parameters created through the Tools>Relations command override parameters created through the Parameters command.
