BRep

OCCT package BRep: BRep_Builder, BRep_Curve3D, BRep_CurveOn2Surfaces, BRep_CurveOnClosedSurface, and 17 more bound classes.

BRep_Builder

TopoDS_Builder

A framework providing advanced tolerance control. It is used to build Shapes. If tolerance control is required, you are advised to:

  1. build a default precision for topology, using the classes provided in the BRepAPI package
  2. update the tolerance of the resulting shape. Note that only vertices, edges and faces have meaningful tolerance control. The tolerance value must always comply with the condition that face tolerances are more restrictive than edge tolerances which are more restrictive than vertex tolerances. In other words: Tol(Vertex) >= Tol(Edge) >= Tol(Face). Other rules in setting tolerance include:
  • you can open up tolerance but should never restrict it
  • an edge cannot be included within the fusion of the tolerance spheres of two vertices

BRep_TFace

TopoDS_TFaceTopoDS_TShapeStandard_Transient

The Tface from BRep is based on the TFace from TopoDS. The TFace contains:

  • A surface, a tolerance and a Location.
  • A NaturalRestriction flag, when this flag is True the boundary of the face is known to be the parametric space (Umin, UMax, VMin, VMax).
  • An optional list of triangulations. If there are any triangulations the surface can be absent.
    The Location is used for the Surface.
    The triangulation is in the same reference system than the TFace. A point on mySurface must be transformed with myLocation, but not a point on the triangulation.
    The Surface may be shared by different TFaces but not the Triangulation, because the Triangulation may be modified by the edges.
