Hi All,

I work for an Aluminium system company and I’m currently in the process of creating all our products (Curtain Walling, Windows, Doors) as Curtain Panels & Mullions. Creating the families and profiles is going well but i am having an issue where i am trying to get the Parameters on a System Family: Curtain Wall to be different on each screen/group.

For example i have a System Family: Curtain Wall called "100mm Ladderframe" and I want to use it on every curtain walling frame on a project. All the mullions, panels etc are the same but I want some of the Parameters to show a different value on each group/screen. At the moment if i change a parameter value it changes it on every frame.

Its only text parameters i need to change, things like ReplacementCost, InstallationDate, Spareparts etc (For COBie)

Is there a way for me to do this or do i need to create a new System Family: Curtain Wall Type for each frame? So 100mm Ladderframe Type 1, 100mm Ladderframe Type 2 etc etc...

Or have i done somthing stupid like set the parameters up incorrectly?



Apologies if this is a really simple/obvious thing but I don’t have much experience with Parameters so everything is a bit new to me. For reference I am currently using Revit 2013.

Thank you in advance

-Karl

In order to change text via parameters you need to first make a 'generic annotation' family and then add a label to it. Labels are only available in annotation template families. Once the label is in the family you can add a parameter to change the text. once this is done you need to load it into your curtain panel family and link the label parameter to a text parameter in the panel family.

Also it seems you want to create different types and have the parameters set as type parameters.

I'm going to have to disagree with marmiketin1 here. 

Not sure exactly what your question is.   You can assign project (shared) parameters to curtain wall elements and those parameters are then available to be tagged and/or scheduled.  If that parameter is instance, it can change no matter what the family type is  <<< This is what you want.  Then if you want a visual text in say an elevation, you need the appropriate tag that is set to read this instance parameter.

Marmiketin's answer is for a nested annotation - not sure were the poster is using that.

Ahh yes shared parameters would be better. I didnt even think of that. The only place i use nested annotations is in window and curtain panel families as GL in the glazing which only appears at certain view scales and in elevation
