By creating Section Relations that refer to the Trajectory Parameter (trajpar), you can cause the dimensions of a Variable Section Sweep to vary along its Spine Curve, according to a mathematical function. A simple example is shown below: the width of the protrusion is determined by a parabolic function along the length of the feature.

You can create a datum feature that is used to measure the distance between two faces in a part. Since the datum is a feature, it updates each time the model regenerates. An Analysis datum is not displayed on the screen, and has no geometric description; however, you can select it in the Model Tree.

Many designs can be driven by a single parameter. In doing so, you force the part to change only as you intended when you designed it. For example, if a part must always fit into a specific space, you can define relations in such a manner that the overall size cannot exceed a desired value.

After you create a Layout you can Declare it to any number of parts or assemblies. Once declared, the part/assembly inherits the parameters contained in the layout . You can then write relations in the part/assembly to utilize the parameter to drive dimensions.

An Analysis datum has a feature name and can contain an unlimited number of measurements. Measurements are also given a parameter name. Once an Analysis Datum feature is defined, you can refer to it in a Relation using the following nomenclature:

After the creation of the Pro/E model, identify dimensions that are crucial to the functionality of the designed part, then create design parameters and associate them with these dimensions. In our example, the key dimension for the flexure is center thickness of the tapered beam.
