Is there any way to get the height of tag?
If you’re trying to get it from inside a Revit project, you’ll have to open up the family, select the label, and get the “Text Size” parameter from it’s family type.
i need to get it without open the family
@shibujoseukken do you have the Revit Lookup addin installed?
Click the element and check with this addin the parameters.
But don’t forget, this is a family parameter.
Good luck
