Part

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

Bases: compas.datastructures.datastructure.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 (list of tuple(compas.geometry.Shape, str), optional) – The features to be added to the base shape of the part geometry.

Attributes

• attributes (dict) – General object attributes that will be included in the data dict.

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

• transformations (deque of 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.
