Curves and Edges
Datum curves, surface edges, and solid edges are represented in the same way in Creo Object TOOLKIT Java. You can get edges through geometry traversal or get a list of edges using the methods presented in the section ModelItem.
The t Parameter
The geometry of each edge or curve is represented as a set of three parametric equations that represent the values of x, y, and z as functions of an independent parameter, t. The t parameter varies from 0.0 at the start of the curve to 1.0 at the end of it.
The following figure illustrates curve and edge parameterization.
