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: Embodiments of the invention provide a technique for rendering components included in a computer-aided design (CAD) drawing of a utility network, such as system of pipes and related equipment. Display settings may specify whether a particular component should be rendered using 2-line, 1-line or graphical 1-line display representations, based on the size of that component in the CAD drawing.

Abstract: A method, apparatus, and article of manufacture provide the ability to update a slope of a run in a system in a computer drawing application. A system run (i.e., an interconnected series of objects) is selected in a computer drawing application. The objects in the interconnected series are part of the same system and the series has a starting point and an ending point. A property for a slope of the system run is specified. The slope of the system run is updated across all of the interconnected series of objects based on the specified property.

Abstract: Methods and apparatus, including computer program products, for providing a physical computer aided design (CAD) model comprising a plurality of physical objects in a flow system. Each of the plurality of physical objects are joined at one or more physical linkages. An analytical model of the flow system is generated based on the one or more physical linkages. And one of the analytical model or the physical CAD model is automatically updated to reflect a change to the other.
