Using parameters of a tagged object to drive parameters within the tag

[LOESCH_PK]

This is a tricky one. Is there any way to use parameters from a tagged object to drive paremeters in the tag itself? I don't mean showing them in labels of course. 

The exact problem is: Creating a wall tag that will draw a line as long as the wall that it is tagging.

Sounds like a shear wall tag? Tags don't provide us with instance variables to stretch the symbols. Also since they don't change when a view's scale is changed the calculation to adjust the length of such line is a variable that also requires knowing the view's scale to work it out.

I've built a line based family in the past that provides first and last pick points to describe the length of a wall and includes the shear wall ID information. For that I think we just entered the shear wall type value manually after placing it so it wasn't determined by the wall type it is touching. That's because they weren't drawing different wall types at shear conditions so one wall wasn't any different from another, nothing useful to try to extract.

With Dynamo you could do some parameter matching based on wall type and shear marker type and plug in the same type value based on the shear wall and the annotation being next to each other or having matching start and end points...some logical criteria to help define their obvious relationship.

If this is really about a shear wall, see attachments (file is old 2009 or earlier).

Thank you Steve, but this is not really what I'm looking for. I wanted to have an easy way to show on my floor plans fire-resistant walls of different classes. I can easily auto-tag all the walls with a fire-resistance parameter by selecting then via a filtered schedule and then tagging all with a rotating to object tag. This tags all the fire-resistant walls in their geometrical middle. And this is pretty ok.

But my company would like to show them with a line going threw their entire length with a tag with the fire resistance value popping up every now an then. If the tag could read the wall length and use it to create a line, and maybe add an array of labels along it that would be perfect. But as you mentioned, the line length would have to take in account the scale of the drawing. This is probably not the way to go.

My other idea is to create a line based annotation object with a line an an array of text notes (with values like the fire class) and then use Dynamo to find walls on the view of appropriate class and draw a line exactly where the wall is.

I could just also make a separate drawing that uses filters to colour walls of different classes, but that would be to simple for officials. 😛

Isn't this usually done with fill patterns?
