Zebra analysis, which is found in some other packages, plots zebra stripes over your model as if it were chromium-plated and placed inside a striped cylinder. One problem with zebra stripes is that as you change your view of the model, the stripe patterns change so it can be difficult to analyze blends from several different angles. G2 surface matching is absolutely essential for product and transportation designers. Vellum Solids 2000 adds eight new solid blend types and nine new solid chamfers. You can now add a draft angle to a solid swept along a path.
Most surface editing commands have solid editing counterparts.
Particularly impressive is the ability to loft between two different solid profiles, smoothly transitioning from one to the other, all with G2 continuity. Vellum Solids already had an amazing set of curve tools. In addition to conics, there are vector splines, b-splines, and Beziers. It's difficult to come up with a design that you couldn't model efficiently with one of these. The new Convert Object Type command lets you change rational curves such as circles and ellipses to vector splines, to which you can add control points to modify their shapes.
