Class Entity142_CurveOnSurface

  • public class Entity142_CurveOnSurface
extends GeomSSEntity
    CURVE ON A PARAMETRIC SURFACE ENTITY - This entity represents a curve associated with a surface and identifies the curve as lying on the surface.

    This entity, when read from an IGES file, is converted to a SubrangeCurve curve. This entity type can be written out to an IGES file. When reading in this entity, the IGES parameters are stored in the user data with the prefix "IGES_142_" followed by the parameter name.
