- ...intersect
- This condition also allows us to express contour
relationships in a tree fashion. e.g. ``Feature A is a child of Feature
B''.
- ...pockets
- ``profile'' features can be defined by arcs,
lines, and piecewise parametric cubics, linked end to end to form complex curves.
- ...features
- The
reader must be careful to distinguish between mechanical or machined features and visual or geometric features.
