Part

class compas.datastructures.Part(name=None, frame=None, shape=None, features=None, **kwargs)[source]

Bases: Datastructure

A data structure for representing assembly parts.

Parameters

• name (str, optional) – The name of the part. The name will be stored in Part.attributes.

• frame (compas.geometry.Frame, optional) – The local coordinate system of the part.

• shape (compas.geometry.Shape, optional) – The base shape of the part geometry.

• features (sequence[tuple[compas.geometry.Shape, str]], optional) – The features to be added to the base shape of the part geometry.

Attributes

• attributes (dict[str, Any]) – General data structure attributes that will be included in the data dict and serialization.

• key (int or str) – The identifier of the part in the connectivity graph of the parent assembly.

• frame (compas.geometry.Frame) – The local coordinate system of the part.

• shape (compas.geometry.Shape) – The base shape of the part geometry.

• features (list[tuple[compas.geometry.Shape, str]]) – The features added to the base shape of the part geometry.

• transformations (Deque[compas.geometry.Transformation]) – The stack of transformations applied to the part geometry. The most recent transformation is on the left of the stack. All transformations are with respect to the local coordinate system.

• geometry (compas.geometry.Polyhedron, read-only) – The geometry of the part after combining the base shape and features through the specified operations.

Class Attributes

operations (dict[str, callable]) – Available operations for combining features with a base shape.

Methods
