How can I create a tag to show the height at the centre of the pipe?

[KathleenMEP]

I'm working on our first Revit project at the moment.

I want to create an annotation tag that will show the height of the pipe at the centre. I can find how to tag the inverted elevation and I've tried spot elevation but I can't figure out the centre.

I just want it to show the height you select under "offset" when drawing the pipes.

I'm sure there must be a really simple way of doing this (I hope) that I just can't find.

Any advice would be much appreciated.

I'm surprised you haven't gotten any feedback on this thread yet.
Surely there will be a more REVIT appropriate solution, which I can't help you with specifically.

If I wanted to do something like this in Autocad Vanilla, I would probably create an MTEXT item,
and insert a field into it, which would access the information from the selected object.

Hi Dadgad, thanks for replying.

I have tried creating a tag, but when I insert the label and it comes up with a list of fields I can choose from the only one I can see is inverted elevation, which I think is the bottom of the pipe. If I select the pipe though it does tell me the offset height, I just find a way of putting that information into a tag.

I did try searching forums and Googling but I can't find anything, I wonder if you can't do it because there isn't a need for it?

[Dadgad]

I'm sure there will be a way to do it.
One of the Revit users will come along eventually, and be able to help you.
Are there tool palettes in Revit, if so check there, on ANNOTATION perhaps?

Still not having any luck figuring this out. Can anyone help?

I'm new to Revit also. There is an option for "Start Offset" but if your pipes are sloped and you are looking for a spot elevation that is not going to do it.

Rob thanks so much that's all it was!

Sorry I didn't see this topic earlier. We had the same need at my current employer...

If your pipe is sloped, you will run into issues. Start Offset is the height at one end. End Offset is the height at the other end. To get the middle requires a formula.

You need to create a shared parameter with the formula: =(Start Offset + End Offset)/2

...then assign that parameter as your field for the tag.

That would give you the average offset of a sloped pipe. Not sure how that would be useful.

She needs the height at the center of the pipe, correct? Lowest offset plus highest offset divided by two gives the offset (height) at the center of the sloped pipe. The exact center is the mean of the two ends; simple algebra.

This can be furthered by adding or subtracting half of the diameter (the radius) of the pipe to get the top or bottom elevation, respectively.

Unless I'm misunderstanding her need?
