Detailed Description

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.
Map3DEdges : A method to map all the 3D Edges of a Shape.
Dump : A method to dump a BRep object.
