About creating theoretical intersection curves
About creating theoretical intersection curves (and feature curves approximations) that can later be used for surface development.
An input curve (as an approximation of the feature curve) and radius of influence must be provided to calculate the theoretical intersection curve. If you do not have such a curve, you can input a series of points along the feature to create an approximation to the feature curve.
The output consists of a theoretical curve, and, if using the point method, a feature curve approximation. The feature curve attempts to lie on the mesh as much as possible. The theoretical curve is drawn where both sides of the mesh (across the feature curve) would intersect if they were extended. The theoretical curve generally lies off the mesh.
