Namespace:  ModelExchanger.AnalysisDataModel.Subtypes
Assembly:  ModelExchanger.AnalysisDataModel (in ModelExchanger.AnalysisDataModel.dll) Version: 1.13.0+Branch.master.Sha.d583fc64569355d188a9c0818d257b6d0d3e1339
Syntax
C#
Copy
public sealed class BoundaryRepresentationGeometry : IEquatable<BoundaryRepresentationGeometry>

The BoundaryRepresentationGeometry type exposes the following members.

Constructors
  NameDescription
Public methodBoundaryRepresentationGeometry
Create a new BREP geometry definition by providing the vertices & faces that define the BREP
Top
Properties
  NameDescription
Public propertyFaces
The faces of the geometry. Each face contains a list of indexes, which refer to one of the vertices defined in Vertices
Public propertyVertices
The vertices that define the geometry.
Top
Methods
  NameDescription
Public methodEquals(BoundaryRepresentationGeometry)
Compare this instance against another instance for equality
Public methodEquals(Object)
Compare this instance against another object
(Overrides ObjectEquals(Object).)
