    Vertical Clashes in Navisworks

    I thought I could find a parameter that picks up if an element is vertical or not... no such luck.

    I've seen a convoluted method of trying to filter it down once you've clashed say pipes and floors.

    Is there a better way of quickly isolating vertical elements (pipes/ducts) that go through floors?

    Research the Inclusive option under your clash results. Select the slab and it'll isolate only items clashing with the slab itself. The way you set up the clash test helps too.

    Won't that pick up horizontal as well? Those are the ones I want to pay attention to. Vertical, not so much.

    My google-fu has been coming up short on this topic.

    Do you want to review pipes or ducts going through floors? Or are you not wanting to review pipes or ducts going through floors? Can you clarify? Thanks.

    I don't want to review vertical elements (ducts/pipes) going through floors.

    I do want to review horizontal elements (ducts/pipes) that overlap with floors.

    Gotcha. This would be a little difficult to do. There may be a way, but I haven't found it yet.

    I've tried isolating native OOTB parameters from Revit such as Start/End Offset values, Slope, etc. I have never been able to really distinguish between vertical and horizontal MEP system families. The problem with the Slope parameter is that anything that is 0/12 slope is horizontal, but Revit also reads perfectly vertical systems as 0/12 slope. And there's no way to do a greater than/less than with the Slope parameter in Navis Find Items search tool.

    The wall I hit with Start/End Offsets, is that you have to search specific values. If both Start and End Offsets are the same, then it's horizontal, but you can't tell Navis to find all equal or non-equal values for each object.

    I still think my previous suggestion works, as it works fine for me - you'll just have to use the Inclusive selection tool to grab each item and Group them for better managing. Doesn't take that long; I do it quite often. And there shouldn't be a ton of vertical systems going through slabs anyways; if you consider open chases don't apply, that only leaves a handful of systems left that should be going floor to floor and they'll be easily identifiable.

    Not sure this helps you any. Hope you do find a way - I would love to incorporate this into my workflow as well.

    If you wouldnt mind the extra step, and wouldnt mind setting up some rules for what YOU would consider vertical, horizontal, or "close to vertical" and "close to horizontal," ill bet this could be done with a Navis search set reading a Shared parameer, and Dynamo populating the shared parameter of the pipes based on the vector between start point and end point.

    That's the thought process I was going through Tannar. There was the slope parameter, but vertical elements are still 0. There are vertical and horizontal parameters, but those don't help. I'll have to dig into the inclusive option a bit further and try and get it to work.

    Interesting Aaron... that requires me to open Dynamo <starting to cry>. In house mechanical I could pull that workflow off fairly easily. Outside mechanical might be a bit trickier IF I wanted them to create their NWC's. If it was fairly easy and it increased the coordination, then I could easily justify doing the NWC's myself (not like I haven't done it before).

    Well, its only hard when you are MAKING the graph, and setting up the workflow.

    After that, its just:
    1. Open File
    2. Open Dynamo
    3. Open Graph
    4. Click Run
    5. Export NWC's

    Then again, it might not be as simple as i think in Dynamo. brb.

    So, i was wrong... Its even easier than i thought it would be.

    Vertical and Horizontal Pipes both "dont have slopes," but they are shown differently in Revit and Dynamo:

    Horizontals have an actual slope of "0".
    Verticals have an actual slope of "Not Computed" aka <blank> or "". So you can search for- and find- that, and write data to the pipes with the Slope set to "".

    I had intended to do a more elaborate "compare start point and end point Z's" and then also compare start and end point X's and Y's, so you can create "wiggle room" and call "any pipe transitioning more vertical distance than it does horizontal, a "Vertical" pipe," which is still doable.

    But straight Verticals? Yep, you can do it in about five minutes.
