class compas_occ.brep.BRep[source]

Bases: object

Class for Boundary Representation of geometric entities.

Attributes

• shape (TopoDS_Shape) – The underlying OCC shape of the BRep.

• type (TopAbs_ShapeEnum, read-only) – One of {TopAbs_COMPOUND, TopAbs_COMPSOLID, TopAbs_SOLID, TopAbs_SHELL, TopAbs_FACE, TopAbs_WIRE, TopAbs_EDGE, TopAbs_VERTEX, TopAbs_SHAPE}.

• vertices (list of BRepVertex, read-only) – The vertices of the BRep.

• edges (list of BRepEdge, read-only) – The edges of the BRep.

• loops (list of BRepLoop, read-only) – The loops of the BRep.

• faces (list of BRepFace, read-only) – The faces of the BRep.

• orientation (TopAbs_Orientation, read-only) – One of {TopAbs_FORWARD, TopAbs_REVERSED, TopAbs_INTERNAL, TopAbs_EXTERNAL}.

• frame (Frame, read-only) – The local coordinate system of the BRep.

• area (float, read-only) – The surface area of the BRep.

• volume (float, read-only) – The volume of the regions contained by the BRep.
