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 (Frame, optional) – The local coordinate system of the part.

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

• features (sequence[tuple[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 (Frame) – The local coordinate system of the part.

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

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

• transformations (Deque[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 (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

add_feature	Add a feature to the shape of the part and the operation through which it should be integrated.
to_mesh	Convert the part geometry to a mesh.
transform	Transform the part with respect to the local cooordinate system.

to_json	Serialize the data representation of an object to a JSON file.
to_jsonstring	Serialize the data representation of an object to a JSON string.
validate_data	Validate the object's data against its data schema.
validate_json	Validate the object's data against its json schema.
