In this chapter, we consider various approaches to part design and emphasize useful strategies. Specific advanced part modeling techniques covered include multi-body design, advanced lofts, advanced sweeps, coils, and surface modeling.
Advanced Part Modeling Loft Feature Blend of profiles of varying cross section Planes on which profiles are sketched are usually parallel, but any nonperpendicular planes can be used Lofting Process workplanes sketch loft Duplication of Part Features Mirror Pattern (Array) Rectangular Radial Mirror Features Must specify: Features to be mirrored Mirror plane Shell A placed feature no sketch required Used to remove material from interior of a part Cavity created with walls of a specified thickness Selected faces can be removed to form a shell opening Advanced Part Modeling ...
