NMDOT Parts Catalog Part 2

NMDOT PARTS CATALOG – PART 2

DEVELOPMENT REPORT

2.0 METHODOLOGY The process for creating a complete C3D Pipe Network Catalog includes several steps and utilizes additional Autodesk software. Figure 2 shows the basic workflow of this process.

Autodesk Inventor

Create custom parametric structures

Autodesk Infrastructure Parts Editor

Export custom parametric parts from Inventor to C3D

Create standard shape inlets and manholes

Autodesk Civil 3D

Create new Pipe Network styles and layers

Create pipes in Part Builder

Figure 2: Workflow

The list of parts was created based on the parts listed in the NMDOT Bid Item List and the drainage structures in the Standard Drawings. Additional pipe sizes, such as plastic and concrete elliptical, were added to the list. Not all parts from the Bid Item List and Standard Drawings are included in the list of parts. Exclusions are discussed in Section 4.1. 2.1 INVENTOR Autodesk Inventor 2024 was used to create custom parametric models of various NMDOT structures. Key dimensions for the structures were stored as user parameters in the Inventor models. This allows these dimensions to be altered in Civil 3D. The models are dimensioned from the NMDOT Standard Drawings and detail the important permanent features of the structures. Details such as reinforcement, anchors, small footings, grates, and other minor features are not included in the models. Typically, the catalog will be used in design plans, so the resolution of the model will not be high enough for these minor features to be visible. Workarounds with the way structures are modeled are implemented because, by default, Civil 3D only intends for structures to be either an inlet or manhole. Two Inventor parts—the surface structure and the underground structure—are created per structure because of how they interact in Civil 3D. The surface structure is the piece of the overall structure that meets the ground surface. For example, the surface
