    Leader position on Ceiling Tag family

    We have a ceiling tag that is used for reporting either the actual ceiling height, or just calling out "Bottom Of Structure". In the family I have the Ceiling Type Mark with some lines and masking region to make the shape of the tag, and then under that I have overlapping the ceiling height parameter as well as a piece of text indicating "B.O. Structure" with yes/no visibility parameters for each.

    When I have it set to B.O. Structure, the leader line comes off the point of the diamond tag shape, which is ideal and looks best. But if I change it to show the ceiling height, the leaders moves down to come off the midpoint of the family's overall vertical extents. Why the change? I'd love to be able to have the leader come off the point of the diamond for both tag types.

    Posting images separately since that seemed to be breaking the forum a couple weeks ago.

    The actual family looks like this with everything turned on.

    You may want to add an 'invisible line' where your vertical ref plane is, that is long enough (at the top) to keep the point of the diamond centered on it. This way, that invisible line defines the vertical extent max, regardless of which text option you choose, and will keep the leader positioned appropriately.

    As for WHY it's jogging the leader, perhaps there is a return/space in one of the label options that is changing the overall vertical extent between the types.

    The Leader is always going to come off the middle of the top, right, bottom or left based on all the graphics in the Tag family.
    Frankly, what I can't figure out is why it DOES work the way you want on the B.O. Structure one.

    I hadn't realized this before, but just did a little test.
    The leader comes off the middle of the VISIBLE graphics.
    If you have something is the family whose Visibility is controlled by a Yes/No parameter, and the Visibility is No, that element will not affect the Leader
    This is the same Tag. Two Types. One with the "Visible" label Yes, and one with it No

    From what I've found, that is only true for text objects. Any linework that is turned off with still affect the position of the leader. But the last time I tested that was in Revit 2017, maybe it's changed since then.

    There is not. The ceiling height label is wide enough to not have any returns to a second line in it.

    Yeah see that's the thing. There's text there in my tag either way, whether it be a text object or a label. If it was a label or text object actually being turned off with nothing else showing, then I would understand the leader working as desired. It's the fact that it works differently even when there's always something underneath the tag is what's baffling to me.

    Aperte nailed it. You need something above the symbol that ends an equal distance to the bottom of the text thus making the center of the tag at the point of the diamond. Invisible lines work for this but you need to add a type parameter to change the length so that the center is at the desired location.

    But that still doesn't explain my issue. There is nothing above the tag in either case of my 2 attached images in the OP (3rd post shows the actual family). One shows ceiling height, the other shows a piece of text. Leader looks correct when the ceiling height label is turned off and the text is on, but does not look correct when it's the other way around.

    It does explain it.

    The "extents" of Labels and Text are not the same. Meaning the center point SHIFTS when you switch between Text and Label. Why not just post the ceiling tag, and we can show you?
