Revit Duplicates in Navisworks Model

[Anonymous]

Hi,

Can anybody find a solution to this please.

Create a stairs in Revit using the 'Stair by Component' rather than the 'Stair by Sketch'

Export Revit model to NWC

Result: Duplicate instances of the stairs in Navisworks, leading to a pain in the head when Clash detecting.

Anyone?

Revit 2015

Navisworks Manage 2015

What's your search set criteria for stairs? have you added the stairs as selection or search set? what's the selection A and Selection B of your clash test?

There are no search sets. Each discipline has it's own model. I am clashing model A against model B.

well, The solution will be as follows: 

1- Create a search set called all stair components which includes all the stair components. no.1

2- run your clash. 

3- go to the sets panel and select the set we have just added and select first clashing object found with the stairs. 

4- go to the results tab in the test pane and change the none filter into exclusive as indicated here by no.2 ; this will summarize all clashes of this element with the stairs.

5- bind all found results to a result group called Stair clashes. no.3 

6- Do the same with any new element clashing the stairs. 

highlight this answer as a solution if you find this solves your problem.

Thank you for this. But it is a workaround i had thought of but i does not fix the problem. 

Ideally i would like a fix for this problem so that we do not get duplicates in the NWC file in the first place.

I don't think that you can do this inside of Revit before exporting, also there's no way inside of Navisworks to group elements as one unit, that will contraduct with the Element IDs based detection and solution.
