Extrusion

class compas_ifc.representations.Extrusion(profile, direction, depth, frame=None, name=None)

Bases: Geometry

A solid defined by sweeping a 2D profile along a direction.

Directly corresponds to IfcExtrudedAreaSolid. 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. A Polygon for simple closed profiles, a Circle for circular profiles, or a (outer, [inner, ...]) tuple for profiles with voids.

directionVector

Unit direction of the extrusion (in local frame coordinates).

depthfloat

Length of the extrusion along direction.

frameFrame, optional

Local placement of the extrusion solid. Corresponds to IfcExtrudedAreaSolid.Position.

namestr, optional

Optional name for the extrusion.

Attributes:

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

The swept 2D profile.

directionVector

Extrusion direction.

depthfloat

Extrusion depth.

frameFrame

Local coordinate frame.

namestr or None

Optional name.
