We use a good deal of Generic Annotations and often stem multiple Leaders from a single instance. An annoying aspect of removing a Leader is that Revit always removes the last Leader created. In Revit 2013, one can select a specific segment of a dimension string via mouse-over+TAB and delete only that segment. I would like to see this same functionality regarding the Leaders of Generic Annotations.
For example, in the image below, I want to remove the Leader that is pointing to nothing (the elements was removed in a design revision). Unfortunately, that was the first Leader that I created, so by selecting the Annotation and clicking Remove Leader, one of the other Leaders would be removed and then I have to adjust the first leader to replace the lost one. If I could TAB+Select that unwanted Leader and click Remove Leader or press the Delete key, that would be much less of a pain.
So does this functionality extend to any TAG? I was just about to add a wish to be able to Add Leaders to Tags in the same way you can add leaders to Text.
Tags would be a completely different story. I wouldn't want to add dumb leaders to a Tag, but rather leaders that still maintain an association with the Tagged element. This is how I would want Multi-Leader Tags to work:
Say that two nearby elements are Tagged, and I want to combine their Tags into a single one with multiple leaders. Provided that the Tags' Reported Data is IDENTICAL (that is, every label in the Tag reports the same value), then one of the Tags could be moved on top of the other. This would automatically lock (constrain) the Tags together, so if one is moved, the other will remain in the same exact position, maintaining the image of a single Tag. The leaders would maintain independent association with their respective elements.
If one desires to split the Tags apart, their would be a option to do so while the element (the Tag) is selected. Additionally, the Tags would automatically be split should the reported data of either of the tagged elements change. This splitting would offset one of the Tags so they are no longer overlapping.
