Revolution

class compas_ifc.representations.Revolution(profile, axis_point, axis_direction, angle, frame=None, name=None)

Bases: Geometry

A solid defined by revolving a 2D profile around an axis.

Directly corresponds to IfcRevolvedAreaSolid. Preserves the parametric data that is lost when ifcopenshell evaluates the shape into tessellated or OCC geometry.

Parameters:

profilePolygon | Circle | tuple[Polygon, list[Polygon]]

The swept 2D profile. Same conventions as Extrusion.

axis_pointPoint

Origin of the revolution axis (in local frame coordinates).

axis_directionVector

Unit direction of the revolution axis (in local frame coordinates).

anglefloat

Revolution angle in degrees (IFC convention). Use 360 for a full revolution.

frameFrame, optional

Local placement of the solid. Corresponds to IfcRevolvedAreaSolid.Position.

namestr, optional

Optional name for the revolution.

Attributes:
