I know this post is really old but did you ever find a solution? I am finding that the leaders just go to the middle of the contents of the tag, regardless of visibility.
But is there a way to get the leader to go to the center of the room number box like the attached?
Only when Room name is short, so short that the text remain in one line and not wider than the width of the box. To top of that, it only works when the leader is to the left, right, or top. Does not work for any other scenario, unless you develop different families for different conditions, which sounds ridiculous. So, I would have to say the answer is No.
Adding for future searchers.
Working with Revit 2018, the workaround seems to be adding invisible lines to trick the leader into the proper position.
Any solution is going to be totally reliant on the contents of the tag, your desired output and justification settings.
The leader appears to follow the text rather than the actual tag box (or triangle) in the case of our Revision Cloud tag.
That's a rather limited test. Try playing with more complex family with multiple types and visibility parameters.
This is unfortunately the trick. Use invisible lines to outline the exact size of the tag you want. Revit will consider the invisible lines the extents of the tag and thus snap the leader origin to the center of them. So ensure wherever you want your leader to snap to is at the center of the invisible lines. Reference planes have no relation to leader line origins.
It is incredible these types of workarounds are necessary at this point for out of the box quality-of-life improvements.
Quality of life? Isn’t that a bit extreme?
BTW, your solution was already suggested.
I'm confirming the solution that works in this thread amongst the many suggested over years of replies, for future users trying to resolve this.
"Quality-of-life improvements" is common terminology for software features that don't significantly redefine the product, but simply provide general ease of use for the user's day-to-day experience.
Thanks for the reply!
