BRepTools Class Reference

The BRepTools package provides utilities for BRep
data structures.

* WireExplorer : A tool to explore the topology of
a wire in the order of the edges.

* ShapeSet : Tools used for dumping, writing and
reading.

* UVBounds : Methods to compute the limits of the
boundary of a face, a wire or an edge in the
parametric space of a face.

* Update : Methods to call when a topology has
been created to compute all missing data.

* UpdateFaceUVPoints : Method to update the UV
points stored with the edges on a face. This
method ensure that connected edges have the same
UV point on their common extremity.

* Compare : Method to compare two vertices.

* Compare : Method to compare two edges.

* OuterWire : A method to find the outer wire of a
face.

* OuterShell : A method to find the outer shell of
a solid.

* Map3DEdges : A method to map all the 3D Edges of
a Shape.

* Dump : A method to dump a BRep object.
