OCCSurface

class compas_occ.geometry.OCCSurface(name=None)[source]

Bases: compas.geometry.surfaces.surface.Surface

Class representing a general surface object.

Parameters

name (str, optional) – The name of the surface.

Attributes

• continuity (int, read-only) – The degree of continuity of the surface.

• u_degree (list[int], read-only) – The degree of the surface in the U direction.

• v_degree (list[int], read-only) – The degree of the surface in the V direction.

• u_domain (tuple[float, float], read-only) – The parameter domain of the surface in the U direction.

• v_domain (tuple[float, float], read-only) – The parameter domain of the surface in the V direction.

• is_u_periodic (bool, read-only) – Flag indicating if the surface is periodic in the U direction.

• is_v_periodic (bool, read-only) – Flag indicating if the surface is periodic in the V direction.

Other Attributes

• occ_surface (Geom_Surface) – The underlying OCC surface.

• occ_shape (TopoDS_Shape, read-only) – An OCC face containing the surface converted to a shape.

• occ_face (TopoDS_Face, read-only) – An OCC face containing the surface.
