NMDOT PARTS CATALOG – PART 2

DEVELOPMENT REPORT

structure for an inlet would refer to the grate structure. The underground structure is the piece of the overall structure below the invert of the outlet pipe. Everything in between the underground and surface structures is extruded based on the structure port dimensions. The structure port is the connector between both the underground and surface structures. This connector's dimensions control the size of the area extruded in the structure. The connection points between the underground and surface structures, the default insertion point of pipes, and reference points are all locations that can be modified in Inventor. An example of the structure port being added to a part is shown in Figure 3 .

Since there are no restrictions on how certain key parameters can be used in the model, structures of any shape can be exported from Inventor through Infrastructure Parts Editor into Civil 3D. This means that many parameters, such as USDiameter do not necessarily need to be used for manhole diameter. Instead, it can be used as other dimensions in the structure. However, there are some limitations with how the parts can be used in Civil 3D because both a surface and underground structure is required. One example is that the structure port connector must be added above the slope blanket structure because it is modeled as the underground structure. This creates a visible “stick” when brought into computer-aided drafting and design (CADD). This is due to a workaround with the way structures are handled in Civil 3D, where a surface structure is required. This stick is located above where the
