The routing process is the same for cableway, cable tray, conduits, cables, and duct banks. The following terms describe the different objects that you might work with during a modeling session:
-
Run - An unordered list of items that make up the routing entity with which you are working. In other words, the length of your cableway from start to finish.
Leg - A leg is a set of continuously connected features routed in the same direction. You can modify a leg by selecting a straight feature or by using On Same Leg available on the right-click menu. See Get Features Command.
-
Feature - An object that comprises part of a routing entity in the model. You are free to move the feature at any time during the design process. Features are designs with intent; that is, you use features to route the entity to suit your model's design. Features include the following:
-
Along-leg feature - A logical object that represents a feature along the leg of a cable way, such as a tee.
-
End feature - An object that represents either end of the routing entity.
-
Straight feature - An object that represents a straight section of the routing entity.
-
Turn feature - An object that composes part of a routing entity in the model. The turn feature represents a change in direction for the routing entity.
-
Transition feature - An object that represents a change of cross-section of the routing entity.
-
Parent feature - An object that represents a feature that includes an additional feature, such as an insulated straight feature.
-
-
Part - Item selected from a catalog, such as elbows or tees that allow you to turn corners.
-
Port - An open end of a part.
-
Connection - The junction where a port meets the routing entity or another part. The connection can be sealed or unsealed.
-
Connection Item - Items that seal a connection, such as welds or bolts.
-
Boundary connection - A boundary is a port of the terminal object in a select set. Boundaries can exist at line change, run change, branch point, and at split.
