Revit Text Leader with Adjustable Arrowhead Line Weight

A recent post by Mark Cronin got me thinking… if you can control the arrowhead lineweight for Spot dimensions, can we hack one of these to make a piece of ‘text’ with adjustable arrowhead lineweights?  The answer is yes:

Some people want absolute visual control.  If you are one of those people, check out the example file and see if you can figure out how I did it:

Mark also makes this comment:
So it appears as though the ability to control these parameters is indeed there (and has been for years)! But why can’t they be controlled for text annotation and keynotes, where they would be of most use? 

Personally, I wonder whether Spot dimensions are a ‘newer’ element in terms of Revit version, so perhaps the Factory was able to introduce this visual control here, while still being unable to easily add it to existing elements like text.

EDIT 
If you are wondering how to modify the text, you need to access the annotation symbol family that is referred to in the Spot Coordinate type definition:

After modifying this property, you need to drag or just “touch” the spot coordinate to force it to regenerate.

Downloaded you file, I see what you did, but how do I access the “label text” after it is placed in a project? I can make multiple Types if I edit the family, but not after it is placed in a project.

What I’m most interested in is the fact that a normal text label leader DOSE NOT snap to an element, there always free floating. Using this method it dose snap to elements, we just need to be able to edit the text after it is placed.

You need to modify the related annotation symbol – see update in the main post above.

unfortunate there isn't a way to trick revit into allowing changes.
While this trick might work, it just doesn't make sense to have to make a new type for each and every possible note just to get a thicker looking arrow.

Here's hoping 2015 solves this one :/
