How do I TAG a duct to show the RL

[bluelion]

Looking to TAG some duct to show oveall building RL (i.e. height from ground being 0m) instead of EL from related level. Any ideas?

Hi,

Just an idea. Create a shared parameter for the duct with a formula to calculate the height from ground and then use it in a tag. It might work.

Thanks Ali, your idea is a good one and I have thought of the same thing. Although how do you edit the duct family? It is a system family is there somewhere I can do this?

You cannot edit System Families. If you wish to add a Shared Parameter to them, you must add it as a Project Parameter and apply it to those Categories. This means that a formula cannot be used to determine it's value.

Have you tried using the Spot Elevation Tag? It's located on the Annotate tab. I use this to annotation the mounting height of wall-mounted devices because Revit is not able to include this info in the standard Tag. So, I essentially have two separate Tags for the devices in which I need to label the height.

Hope this helps!

Every time I select the spot tag tool Revit crashes LOL!

Well, that's no good! Do you have all the latest service packs?

Not sure will have to check. Someone has told me not to use that button before.........
