I am trying to build a model of a building using precast concrete double tees. The only families I can find in Revit Structure 2012 are listed in structural framing and the tees are listed as being for roof or floor decks. I have figured out how to rotate them to a vertical orientation, but they are still not recognized as walls, so I can't add doors or windows to them. I also have not figured out how to trim a tee at the end of a wall, which you usually have to do to make the walls match up at the corners of a precast building. Any help would be gratly appreciated.

For vertical double tees, I would stiil start with walls and add face based families that define the tees, legs and joints.  That family can be use for counts and dimensioning but let the walls function for windows, doors and corners.

Ok, now I get to show what I don't know about Revit. What is a face based family? Do they already exist in Revit or is this something you have to build your self? If so how do I get started. Thanks

You will have to create the family.  A face based family will be hosted on any face of any object - in this case a wall face.  It would be a simple extrusion, the shape of the tee legs only and should be parametric so that you can set its length (height for vertical). 

BTW - What I am describing is purely architectural elements.  They would not have any structural properties.

The method I used was to make a profile and use it as a vertical wall sweep.  Then join the sweep to the wall.  worked great.
