About the Trajpar Parameter
The trajpar parameter represents a trajectory path in Creo. Its value ranges from 0 to 1, with 0 representing the beginning of the trajectory, and 1 representing the trajectory end. It is used as the independent variable in a relation.
You type a relation using trajpar after you draw the section sketch, while the Sketch tab is still open.
