Editing Pipeway Paths

There are several ways you can edit the pipeway path a route uses:

manipulate the route through the desired pipeways (see Segment/Point Manipulator );
select the starting and/or ending pipeways; and
selecting certain adjacent pipeway pairs that are not to be connected by the router.

Pipeway Selection

From the Pipeline Editor, Electrical Cable Editor, or Connectivity Editor, you can select the pipeways used for a route. Select Modify > Pipeway Route Selection menu, to open the Pipeway Route Selection dialog.

Pipeway Route Selection dialog in both Specify modes.

The Pipeway Route Selection dialog opens in Starting and Ending Pipeways mode. In this mode, starting and ending pipeways are selected for the drop-down lists and must be Accepted to make the changes.

Setting	Description
Set to Default	Reverts the route back to the router’s default pipeway path. If you want to define the full pipeway path, the mode of the dialog needs to be changed to Complete Pipeway Path.
Insert Next	Initially, the Insert Next Pipeway drop down list will list all of the pipeways within the model. After a pipeway has been chosen, only legitimate connecting pipeways will be available for selection.
Delete	Removes selected pipeways from the `Ordered Pipeway Path` list.
Routed Path	Makes changes to selected pipeway to the default pipeway path. You can seed the `Ordered Pipeway Path` list with the existing path by clicking on the Insert `Routed Path` button.
Apply	Saves the changes to pipeway path.
Close	Exit the dialog without saving the changes.

Tip: It is important to note that if the pipeline or cable ends an on-pipeway boundary, the pipeway selected for that end cannot be overridden. Similarly, pipelines that end at a tee to another pipeway pipe cannot have that end’s pipeway changed.

Adjacent Pipeways

As discussed in "Structure Pipeway Routing" in Pipeway Header Sequence , the router calculates virtual pipeways that connect structure pipeways, vertical pipeways, vertical chases, as well as external pipeways to structure pipeways. Because the router calculates every possible virtual pipeway, you can selectively invalidate pipeway pairs in the Pipeway Adjacency Filter opened from the Edit menu of the Pipeway Builder.

Pipeway Adjacency Filter.

Setting	Description
Existing Pipeway	Lists the virtual pipeways in the Existing Pipeway Adjacency Pairs.
Invalid Pipeway Pairs	Lists the invalid pipeway pairs.
—>	Moves the selected virtual pipeway in the Existing Pipeway Adjacency Pairs column to the Invalid Pipeway Pairs column, to prevent the router from using certain calculated virtual pipeways.
<—	Re-enables virtual pipeways by moving them back into the Existing Virtual Pipeway Pairs. Tip: The pairs can also be dragged and dropped to the other side.
Apply	Saves the changes.
Close	Closes the dialog and lose any changes since the last Accept.
