Embodiments of the invention provide a method for generating labels for drawing elements of a computer aided design (CAD) drawing that may include some unknown number of associated or related drawing elements. The method includes receiving a selection of a set of drawing elements in the CAD drawing that are associated with the first drawing element, receiving a selection of fields specifying attributes of the drawing elements in the set of drawing elements to use in generating label content for a label of the first drawing element, and defining a label style based on the selection of the set of drawing elements and the selection of attributes of the of the drawing elements in the set of drawing elements.

Embodiments of the invention provide a method, apparatus and article of manufacture for modeling a variety of three dimensional structures that may be represented as a longitudinal series of repeating cross-sections. In one embodiment, users construct each cross section from a collection of subassembly components selected from a catalog of subassemblies. Each subassembly is represented as a data component that stores modifiable parameters, and a logic component that generates a parameter-specific geometry of the subassembly for use in a cross-section of the model. A graphical user interface allows a user to select a subassembly, to modify the parameters for the subassembly, and to integrate the subassembly element into the computer model.

One embodiment of the invention provides a method for extending a schema of network parts types and part type attributes hard-coded by a CAD application. The network parts may be used to compose a CAD model. Users may extend the network part schema by adding an attribute or property for an existing network part, or define an entirely new part by associating the new network part with a set of part type attributes. At the same time, the CAD application may use either a hard-coded or dynamically assigned enumeration value to perform a variety of functions using both the hard-coded and user declared network part types and part properties. For example, functions such as searching a network part list or traversing the elements included in a CAD model may operate using the enumeration values, allowing the CAD application to perform these operations efficiently.

Embodiments of the invention provide a method for creating a complete 3D model of complex infrastructure configurations, such as divided highways, roadway intersections, etc. Current CAD applications have been limited to creating 3D models based on the geometry of a single alignment. In one embodiment, each baseline for a 3D model using four data inputs: a topographical terrain model, an alignment specifying the longitudinal 2D geometry for the structure being modeled, a profile specifying the elevations of the baseline along the horizontal alignment, and the geometry for cross-sectional assemblies along the horizontal and vertical alignments.
