In an embodiment, a computer-implemented method of creating a 3D-part within a computer aided design (CAD) three-dimensional (3D)-assembly can include, in the CAD 3D-assembly, creating the 3D-part based on user input received in the 3D assembly. The method can further include automatically associating a history with the created 3D-part, the history based on the user input used to create the 3D-part.
