Advanced Covering is a feature of Deformable Modeling that is now available as a standalone add-on for the 3D ACIS Modeler. This single API uses sophisticated algorithms to create high-quality n-sided surfaces that meet user-specified tolerances for position and continuity on boundaries and on optional internal guiding geometry. Advanced Covering allows a surface to be fit onto circuits (collections of edges that form closed loops) in solid or wire bodies, which is useful in consumer product design. Many of our customers use Advanced Covering for end-capping, post-translation corrections, and surface definition from curve data. Some of the capabilities of the Advanced Covering feature include:

• Creation of non-planar, n-sided boundaries
• Retention of positional and tangential continuity with adjacent surfaces
• Individual specification of boundary continuity on each edge (G0 and G1)
• Placement of auxiliary point and curve restraints (G0 only)
• Post-covering gap reporting (diagnostics)
• Specification of initial surface
• Re-covering of faces.
