    Revit & Clash Detection inNavisworks

    what is everybody work out for revit exports to navisworks and doing clash detection. ?

    we export the model to navisworks and then run a clash test using the rules we have set up:

    Steel v Duct
    Steel v Tray etc...

    then go back to the revit model and sort out the clashes.

    then export another model to navisworks and run the tests again.

    just seems like a laborious task having to export and set up the clash tests and go through them everytime

    is there anyway of doing it without having to export everytime, or is there any other programs that maybe do it live from revit?

    Cheers

    I export mine to navis 2-3 times a week. Automated exports go a long way.

    This made me think of https://buildingsp.com/index.php/products/clashmep

    Intersection of objects is also available if running Dynamo to complete a check. It would then come down to the granularity of how you want to show that clash. It would take a lot of time to set up Dynamo scripts to check everything.

    had a look at that before, I mean we do try and and minamise clashes while modelling but some are missed - would be better if navisworks was inbuilt into revit somehow and the test results updated automatically

    I use the CTC Revit Express Tools Batch Suite (Batch Exporter). But i think there are a bunch on the market.

    There is no way i would want to do all of the clash reviewing in Revit. Navigating in revit is like driving a Chevette, compared to Navisworks' ability to navigate around while reviewing Clashes.

    Every time you export, do you have to set up all the sets and clash test? is there a way not to do this every time.

    we have saved sets, and clash test which we load into every export - but surely there must be a quicker way?

    Heavens no. That stuff all lives in the NWF. Only gets set up once. Why would you need to redo that every time? I'm just re exporting NWC's.

    That’s where we are going wrong. Do you just do it once per project.

    What do you do on the next export?

    Everyday is a school day ha!

    So what is it that you do?

    export revit model to NWC, do the intial set up of sets and do a clash test then save as a NWF?

    how do you get the new NWC into the NWF and keep the previous settings.

    Cheers
