    What drives Drag point location?

    Does anyone have some solid rules that guide where the drag marker is placed in a family, specifically a Room Tag if there is some difference?
    To give some context, I am working on a room tag with different types for different finishes shown in a box below. I am trying to use the invisible line trick to ensure that leaders stay centered on the room name, with an invisible line that flexes to "in theory" keep the extents of the family centered. Works great for large "finish boxes" but as the box gets smaller the drag mark doesn't keep moving up, and it seems the drag marker is also part of the definition of extents. End result, the leader is located wrong.

    Is the drag marker not based on the origin of the family?

      Well, I don't think so... Even if I stare at my family, I can't even figure how the drag point behaves.

        Aaron seems to swear by the invisible line trick to "offset" the tag's entire-extents to bring the "origin" back to the original reference plane intersection, but I too have been unable to recreate the behaviour - that (and this is picky) but I don't like how the "invisible" line is highlighted in selection - it gives me that uneasy feeling of frozen layers in .dwg blocks.

          Yeah, I am with Aaron in that I have had good luck with the technique before. This room tag is the first time I have had trouble, but it is also a more complicated shape, and the first room tag use I have tried. My fear is that room tags actually behave fundamentally differently from other families, or the wall tag I had good luck with is the one that behaves differently. :banghead: And of course neither is likely to be documented anywhere. Just hoping the brain trust has some insight.

          As for the line visibility, it is one of those polish things that I just don't think Autodesk cares about at all. In Autodesk's mind a user kludge is an actual feature they don't have to spend money on developing, so run with it. But in the long run, having the family look bad for the .00001% of the time it is selected, to get it to look better the other 99.9999% of the time, is worth it. To the point that if i have to make the line giant and non flexible to get it to work, I will Frustrating that Autodesk's standards are so low, but that has been true for two decades, ain't changing any time soon.

            Aaron does it to control the LEADERS location, and to keep tags from shifting up and down when i switch types that have more stuff, or less (Room tags). It doesnt change where the drag handle is. Our room tag drag handles are at the bottom of the invisible line at the bottom. I dont fight with it, not worth the effort.

              Who is this Aaron you are all speaking off...? :laugh:
              Anyway: they really don't bug me that much. I'm seeing all kinds of placements, some more usable then others. Luckily they respond to the tab-magic too, so this one lingers at the bottom of my that's-irritating-me-so-much-I-want-to-look-into-it-list... Imho they are mostly at the bottom of the entire thing, centered to the middle of ​all the geometry. They get "placed" in the family editor and don't respond to changes in appearance in the project.
