BRepEdge

class compas_occ.brep.BRepEdge(edge)[source]

Bases: object

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

Parameters

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

  • edge (TopoDS_Edge) – The underlying OCC topological edge data structure.

  • adaptor (BRepAdaptor_Curve) – Edge adaptor for extracting curve geometry.
