Top-Down CAD Design

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.

Dependencies are inferred from the claim text.
