BRepEdge

class compas_occ.brep.BRepEdge(occ_edge=None)[source]

Class representing an edge in the BRep of a geometric shape.

Parameters

occ_edge (TopoDS_Edge) – An OCC BRep edge.

Attributes

type (BRepEdge.CurveType, read-only) – The type of the geometric curve underlying the topological edge.
is_line (bool, read-only) – True if the underlying curve is a line.
is_circle (bool, read-only) – True if the underlying curve is a circle.
is_ellipse (bool, read-only) – True if the underlying curve is an ellipse.
is_hyperbola (bool, read-only) – True if the underlying curve is a hyperbola.
is_parabola (bool, read-only) – True if the underlying curve is a parabola.
is_bezier (bool, read-only) – True if the underlying curve is a bezier curve.
is_bspline (bool, read-only) – True if the underlying curve is a bspline curve.
is_other (bool, read-only) – True if the underlying curve is an other type of curve.
vertices (list[BRepVertex], read-only) – The topological vertices of the edge.
first_vertex (BRepVertex, read-only) – The first vertex with forward orientation.
last_vertex (BRepVertex, read-only) – The first vertex with reversed orientation.
curve (OCCCurve) – Curve geometry from the edge adaptor.

Other Attributes

occ_edge (TopoDS_Edge) – The underlying OCC topological edge data structure.
occ_adaptor (BRepAdaptor_Curve) – Edge adaptor for extracting curve geometry.
