Legends and Tags

Well, the first post is concerned about legends. Even in 2011, Revit Legends have some major shortcomings. Most notably: once you place an element in a legend, only materials can be tagged. Other tags do not work. This is bad because once you placed 30 windows, it would be REALLY important to be able to assign a type mark tag to them. Same with doors, and whichever other elements you are working with.

This is probably derived by the fact that Legends were designed to allow users to make Symbol legends, you know? One of the first sheet in any Architectural set shows a legend of all graphic symbols used in the project, including notes with leaders pointing to the symbols main elements. Now, what we actually need are two different types of legends: an annotation legend and a model legend. The annotation legend would be just like the one currently implemented, where you can drag symbols (including tags) and describe them. The model legend would be a legend that allows you to drag model only elements, and actually tag them as if they were placed in the model. Well, at least tag their type parameters...

There are a few tutorials, out there (like this one), which explain how to create a custom shared material parameter, and assign it to the door panel of your doors, for example. Then you create one panel material for every type of door, with a different note for the door type. In the Legend you tag the doors with a custom made tag, which displays the shared custom parameter. This tags will update automatically if in the future you change the value of the custom door type material parameter...
The problems are: you need to create a material for every door type, which makes no real (BIM) sense, since you will end up with 20 or 30 "Door - Panel xx" materials, which are all the same color, finish, etc, except the custom door type parameter. If you actually use your materials assignments for rendering (either Revit or MAX), this can be a material managment nightmare. Not to mention materials take outs in Revit.

Someone came up with a very creative way to display the type number in legend, but probably this workaround is simply too much to be feasible.
It involves placing a 3D model text, and linking its content parameter with the paramter you wish to display. I need to find the tutorial, and I will link it for your reference...
