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: In one embodiment, a computer-readable medium is configured to store instructions for creating a model in a three-dimensional (3D) environment, where the model represents a real-world object. The instructions, when loaded and executed by a processor, causes the processor to, given a two-dimensional (2D) sketch comprised of sketch entities, automatically create one or more 3D part in the 3D environment corresponding to respective groupings of sketch entities. The instructions further cause the processor to create a derived layout sketch in the 3D environment associated with a first 3D part, where the derived layout sketch is a reference to or a copy of the 2D sketch, and automatically create a relationship between the first 3D part and a second 3D part where the relationship is based on a constraint between corresponding respective groupings of sketch entities.
