I'm working on a Wall Opening family that will have the potential of (2) symbolic lines:

• one for the Wall Lintel
• one for the Veneer Lintel (as required)

I'm using shared parameters in hopes of being able to setup a helpful schedule.

And furthermore, I want to be able to TAG these openings, using only ONE tag family to accomplish a couple of different things: If the wall has NO VENEER, then the tag would simply report the value for the Wall Lintel.  If the wall DOES HAVE A VENEER, then the tag would report the Wall Lintel type AND "LL" for the Veneer Lintel.  Make sense?

The Veneer Lintel is the only one giving me trouble.

In my Wall Opening family, I've created 2 shared parameters related to the Veneer Lintel:

Veneer Lintel (Yes/No, Instance parameter)

Veneer Lintel Tag (Text, Instance parameter) the Tag is pointed to this parameter

So, I'm trying to set the Veneer Lintel Tag to read "LL" if the Veneer Lintel parameter is checked (True).  I want it to be blank (empty) if Veneer Lintel parameter is unchecked (False).

Am I going about this the right way?

I've read lots of forum threads and I've searched Revit Help, and still can't get it right.

I'm guessing that the formula for Veneer Lintel Tag would look something like:

IF (Veneer Lintel, LL, <empty>

Thanks for your help!

Worked GREAT!  Thanks!

So, how do you create a schedule for this family that was created using the Generic Model Wall Based template?  I can't seem to find the correct schedule type.

 Again, THANKS!!

Well, after a quick search in the Revitcity forums (which I should have done first), I learned from Mr. Spot that the Multi Category Schedule works.  And I'm only using it as a reference schedule at this point.  But, I think you're right about the Category.  I had intended to just use one "wall opening" family for both doors and windows, but right now I'm thinking that I should create a separate family for each using the same elements, but a few different parameters.
