What is evalgraph?
Evalgraph is a system parameter used for driving dimensions in Sketcher relations of swept features, according to a user-defined graph feature. The y-axis of the graph feature drives the dimension as the section travels along the trajectory represented by the x-axis.
Evalgraph is used in conjunction with trajpar.
What is "trajpar" and how is it used?
Trajpar is a value normalized along the origin trajectory of a variable section sweep. The value can vary from 0 to 1 as the section is swept. Trajpar is a trajectory parameter which can be used in a sketcher relation to "map" a graph or any functional
equation along the variable section sweep feature. By using trajpar in a sketcher relation the driving dimensions in the section can be varied as the section sweeps along the origin trajectory.
