Class Entity144_TrimmedSurface

  • public class Entity144_TrimmedSurface
extends GeomSSEntity
    TRIMMED PARAMETRIC SURFACE ENTITY - This entity represents a surface that is a subset of another surface bounded on the outside by a boundary curve and on the inside (holes) with a series of boundary curves.

    This entity, when read from an IGES file, is converted to a SubrangeSurface surface if possible (if the number of boundary curve segments is exactly 4 or can be automatically converted into 4). 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_144_" followed by the parameter name.
