Abstract: A method for mating a user selected first component of a computer aided drafting application assembly to a second component detects a user drag of the first component. A user pause of the drag for a predetermined interval is detected at a pause location. A plurality of first component surfaces and a plurality of second component surfaces are identified. The first component surfaces are compared with the second component surfaces, and a mating is suggested between a first component surface and a second component surface.

Abstract: Maintaining a relationship between a model of an object and data relevant to the model includes storing data representing the model (i.e., the data utilized to construct the model for display by a computerized system), storing user-interface codes for enabling the retrieval of data relevant to the model, forming an association between the model and the user-interface codes, displaying a user interface in accordance with the user-interface codes (the user interface allowing for selection of the data relevant to the model), and initiating the retrieval of the data relevant to the model by analyzing a link associated with the plurality of user-interface codes to determine the location of the data relevant to the model.
