Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for receiving a definition of a version of a part family comprising a plurality of parts, each part having a same shape and a different respective size, wherein the definition includes a set of parameter values for each part of the part family; storing the definition along with other versions of the part family in either a parametric or parametric-independent format; receiving a request for the part family for a particular computer-aided design system; converting a latest version to a different format that is compatible with the particular computer-aided design system; and providing the converted part family in response to the request.

Abstract: Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for identifying a plurality of part families, where each part family comprises a plurality of parts; and for each part in each part family: obtaining connection port geometry information for a physical part in a part family; positioning each of the port vectors in a three-dimensional space at a respective location specified by the port vector; generating a respective port alignment line for each of the port vectors; generating one or more base curves each positioned to align with a plurality of the port alignment lines; generating one or more port solids from the connection port geometry information; and constructing body geometry between each of the one or more port solids by sweeping along a respective base curve, wherein the constructing is based at least on the connection port geometry information.
