Selection Tree Edit

james_andrew_boedijanto — Wed, 10 Sep 2025 12:46:48 GMT

Hey Everyone,

I currently have a rail infrastructure construction project going on in Revit that i want to export only the Views based on the Trades Groups (i.e. Underground Cables, Platform, Drainage) in Navisworks Manage using the NWC Export Utility.
I wanted to have my Selection Tree in Navisworks to show the following order:

Project A.nwd > New Construction View Group (revit) > View Platform Project A.nwc > Building Technique (Shared Parameter_1 Value) > Ramps (Shared Parameter_2 Value) > Element Instance for example.

The current one that i have are either:

1. View Platform Project A.nwc > Revit Categories (i.e. Walls) >>> Element Instances

or 2. View Platform Project A.nwc > Levels (as building floor) > Revit Categories >> Element Instance

Is there a solution on how do i construct the Selection Tree how i want it?

I understand that it is not possible through the Dropdown List. Selection based on Group shows actually what i wanted (I have made the Shared Parameter_1 and _2 as Search Rules), but only from the Shared Parameter_1 and _2 and not more, the first half of the tree is missing.

have you considered using Search Sets instead of the selection tree? I find setting up Search Sets for the specific criteria or element category I am looking for saves a lot of time. the search sets can then be exported and imported into other NWF/D files and reused. i work at a multidisciplinary A/E firm and have a file with about 150 search sets in it with just about everything i typically need. I seldom look at the tree anymore :-).

I have built the Search Set yes, and it works for now. But the task given to me was to make the Selection Tree itself looks like the Search Set, if that makes sense. Because we will be using the Search Set on the 3rd or 4th Parameter Value Search.
For example: 1. Construction Engineering > 1.1 Platform Edge > 1.1.1 Platform Edge Precast Element > 1.1.1.1 Form 55

then the Search Sets will be used starting the 1.1.1

And this has gotten the green light from the client, that thats how they want it to be.

Anyway, i have been trying using Dynamo Python Script to basically override the Family or Type Name with Shared Parameter , so that the NWC-Tree shows our Tree instead of „Kategorie > Familie“. But it has not worked. I may have to re-evaluate that Overriding the Family or Type Name is not the way to go. But how else are we gonna put Shared Parameter_1 and _2 as "top priority list"? All Elements in the View and even the Modell have these Shared Parameter with value added. And the views are the Modell with filtered view (i.e. just Pipes for Underground Pipeline)

Or maybe using Phase is better?

the selection tree is not customizable to my knowledge. All you can do is select the different viewing methods.

Thank you for the clarification. Yes, you are right. I had hoped that maybe through customization of either NWC Export Utility Service from Revit or Navisworks Attach Option or Navisworks .NET API, there will be a way to do it, but so far i have not found it.
