Electrical circuit path

Revit
1

Hello everyone,
I have a number of electrical circuits in my current project (more than 80). The circuit path for all of them is set by default to “Farthest device”. I would like to change all of them with dynamo to “All devices”, but i have not seen any way of doing it.
Does anybody have an idea?
Thanks,
Daniel

Hi @s258085 ,

Is the “Path Mode:” setting a parameter? Because if it is you can use, for example, the node Element.SetParameterValue.

Regards,
Daan

Unfortunately no, “Path mode” is not a parameter.

@s258085 This script will do the trick: Electrical Circuit Path Mode.dyn (8.2 KB)

Hello @s258085 I am trying to use this script but I believe I am having trouble selecting the “Electrical Circuit” Element in the model in order to start the scrip with the right ID#. All I am able to do now is select the Electrical Fixture (i.e. receptacle)

In order to select the electrical cirucit I use the “Categories” node, select “Electrical circuit” and then connect it with the “All elements of category” node. From the list of electrical circuits I select the one I need to as an input for the script.

@AmolShah It works fine in Revit 2020 but ‘Change Circuit Path Mode’ doesn’t work in Revit 2022. Please suggest the solution. Thanks.

Hi, @muhammad.ghufranRA2R
can you show the error ?

Thank you dear. It works perfect.

Guys…For me I cannot select any elements when in dynamo mode…can somebody tell me step by step procedure for dynamo for change edit circuit path from farthest devices to all devices ?
