How to know if pipes are connected or not by a node?

I have transfered a drawing from AutoCAD to WaterCAD V8i and I see the pipes and also de nodes. The problem is that although I see nodes in some pipes that either cross other pipes or that stop (connect) to other pipes, but I'm not sure if there is connectivity or not. How can i check if that node is really connecting both pipes that might be in a "T" or an "X" configuration.

Im in the early part of seting up the model so I can't run it quite yet.

Thanks

  • Yes, the pipes must be connected to the correct end node, as connectivity is based on that. The "split" option when right-clicking the junction will automatically split the pipe that's running behind it but not connected. The end result is that all pipes that appear adjacent to the node will be connected together.

    However, if you have a lot of situations like this where there's a pipe running behind a node and not actually connected to it, you can run the "batch pipe split" tool, located under the Tools menu. This will automatically split all these cases within a user-entered tolerance.

  • To answer your second post, Yes, if all 3 pipes are connected to the node, they should move together when moving the node. Basically you have a single pipe running behind the node, and another pipe that's actually connected to it. Each pipe must have an end node and just because a pipe overlaps a node doesn't mean that they're connected. Connectivity is based on a pipe's start/stop node.

    When you import a CAD drawing, it will not automatically create two pipes instead of one and split/connect to the node. You will need to run the batch pipe split tool mentioned in my previous post. (which will take care of all occurances of this)

    If you have any further questions, please submit a service ticket to technical support.

  • Re: "why ... when transferring my CAD drawing to WaterCAD, it doesn't join ...pipes [it] only puts a floating node?"

    Nodes will only get created automatically at line/polyline endpoints, so what you are seeing in the model corresponds to how the lines were drawn in the cad file.

    Some of the "Floating nodes" could be valid, so we provide a number of powerful review and fix tools (Network Navigator, and Batch Split to name a few) to allow you to interactively review and decide what gets split.

    If you want to split all elements, you can simply run the Batch Split Tool.

    If you want to selectively split some of the elements -- here is the recommended workflow (from online help).

    Pipes will be split by every junction that falls within the specified tolerance. To prevent unwanted pipe splits, first use the Network Navigator's "Network Review > Pipe Split Candidates" query to verify that the tolerance you intend to use for the Batch Split operation will not include nodes that you do not want involved in the pipe split operation.
    To use the Network Navigator to assist in Batch Pipe Split operations
    1. Open the Network Navigator.
    2. Click the [>] button and select the Network Review...Pipe Split Candidates query.
    3. In the Query Parameters dialog box, type the tolerance you will be using in the pipe split operation and click OK.
    4. In the Network Navigator, highlight nodes in the list that you do not want to be included in the pipe split operation and click the Remove button.
    5. Open the Batch Pipe Split dialog.
    6. Click the Selection button.
    7. Type the tolerance you used in the Network Review query and click OK.

  • Thank you so much everyone for the help/tips. Now it makes sense and I will try to use Batch Pipe Split but not before checking the tolerances with the Network Navigator.
