Limitations In Creating Curvature Continuous (Class A) Surfaces In ProEngineer

A Curvature Continuous Check

Curvature continuous surfaces are used on exterior panels of consumer products to aid aesthetic appeal and it also used to improve flow parameters in fluid dynamics problems. Creating curvature continuous (Class A) surfaces has certain limitations. Let us discuss those limitations in detail.

  • To create curvature continuous surfaces, the references such as curves and edges must have curvature continuity.
  • A boundary surface can only be curvature continuous in one direction.
  • A surface created between existing curves in two directions can not be defined to have a boundary condition of tangent or curvature continuous unless all the referenced curves are tangent or curvature continuous with the adjoining surfaces.
