Bottom of Pipe Tag for Revit 2015


I always end up coming back to this one. It isn’t a perfect situation, and you think it would be. The OOTB tags give us an invert elevation tag that pulls that parameter. No BOP elevation is given as a parameter for us to use, so we have to use the diameter parameters and so on. Tag-wise, we can’t add formulas to populate them. All we can do is create a calculated value in a schedule, and that can be tricky to use the right parameters to give us the correct value, often ending up with rounding errors. I am including this link to help explain how Revit actually determines these values, https://aectechtalk.wordpress.com/2014/01/14/understanding-revit-pipe-sizes-and-elevations/

I use the spot elevation annotation in plan and section/elevation views. In plan, I have to tab to be sure I’m snapping to the bottom of pipe. A prefix can be added for BOP. The issue with this is it will not be relative to the level by default; it is relative to the base point or survey point depending on type.

You will need to configure a system tag family with Type settings for a prefix value (BOP:), etc. Then there are instance parameters allowing Relative Base to be the Current Level, or specify a level. Also, Display Elevations can be set to show Top, Bottom, or both values on the tag. Being careful with the tabbing, bottom of insulation can even be selected in plan view. You will need different types created so that you can have different prefix values and text settings for each situation.

  1. Thanks Mohammed, I like your Dynamo solution. For anyone else viewing Mohammed’s YouTube video, he also has a sloped bottom of pipe tag using Dynamo on his channel.

  2. Hi all

    We had the same issue we needed a way to tag the bottom of pipe on all non sloping pipe. The sloped pipe we tag at the ends near the fittings

    I created a BOP Parameter then used an API that i wrote that will get the Bottom of Pipe and populate the parameter. now you can use it on a tag

    If you would like to try it let me know and I will send it to you

    Thanks
