Surfacing Framework

The ACIS Surfacing framework comprises components which facilitate the construction of surfaces and topology built primarily from 3D curves. In all cases, the construction techniques build the required surfaces and topology for a proper closed or open solid body. The surfaces in this framework are generally ACIS procedural surfaces except when analytic representations are possible.

Components

Components	Description
Skinning	This component (`SKIN`) provides techniques for creating surfaces and faces by interpolating a sequence of edges, coedges, or wires, arbitrarily positioned in model space. It is subdivided into: Skinning — A modeling technique which fits a surface through a series of disjoint curves (wire bodies), creating a sheet body or a solid body. Lofting — A modeling technique that starts with a surface and fits another surface through a coedge of the original surface and a series of curves (coedges). Net Surfaces — A surfacing technique which uses a network of curves defining both the u and v surface parameter directions (often called "bi-directional" curves because of this), unlike skinning and lofting which only take curves defining the u parameter.
Covering	This component (`COVR`) is used to fit a surface over the boundary defined with a closed and connected circuit of curves. It generates a sheet or solid body from a set of closed wires or closed circuits in sheet or solid bodies.
Advanced Covering	The Advanced Covering Component (`ADM`) is used to cover (that is, fit a surface onto) closed circuits in solid or wire bodies.
Sweeping	The Sweeping Component (`SWP`) is used to create solid or sheet bodies by sweeping a profile along a path.
