A method, system, apparatus, article of manufacture, and computer-program product provides the ability to generate a cross section for a roadway infrastructure model. A cutting plane line is drawn on the roadway infrastructure model at an arbitrary location. Portions of the roadway infrastructure model that intersect the cutting plane line are determined. Solids are created at the intersections. A cross section is formed by slicing the one or more solids based on the cutting plane line. The cross section is displayed.

Embodiments of the invention provide a method, apparatus and article of manufacture for modeling a variety of three-dimensional (3D) utility networks constructed from individual network part elements. In one embodiment, users may construct a utility network by selecting and assembling a network of inter-connected parts, where each part is selected from a pipe and structure list. Connectivity among parts is established through part placement. Structure and connected pipe properties may be managed as a single property set. As parts are placed in the utility network, auto-sizing logic resizes existing structures to connected pipes. Pipes and structures are represented by part model data that defines a set of common behavior and properties. When a user modifies part model data or property sets or moves inter-connected parts, a logic component resizes and automatically updates any associated two-dimensional and three-dimensional views of the utility network.

Embodiments of the invention provide methods, apparatus, and articles of manufacture for editing network parts present a computer-aided design (CAD) model of a utility network using grips. The network parts may represent elements present in a real-world utility network. Among others, the grips may include a part size grip and a structure rotation grip. When a user selects a part size grip, a graphical user interface may display hash marks to indicate a variety of sizes of the network part provided by a network parts catalog. Dragging the resize grip may cause it to jump from one hash mark to the next, allowing the user to easily select one of the available part sizes. A structure rotation grip may be used to rotate a network part representing a utility network structure about an asymmetric axis.

One embodiment of the invention provides a method for generating a curved pipe object in a computer-aided design drawing where the geometry of a curved pipe object is generally represented as a segment of a helix. A user selects a curved pipe creation method and a set of geometric attributes from which the helix parameters may be determined. From the helix parameters, a display representation of the curved pipe object may then be generated and displayed in the CAD drawing.
