This is an issue that I have run across before.¬† People have asked for¬† a curtain panel with parametric louvers.¬† Well, the closest I can get is a semi parametric louver panel and there are a couple of ways to accomplish this.¬† FYI, this is more of a lesson than a tip… kinda halfway between.¬† There are a lot of steps missing here that the tip assumes you know in order to accomplish these things.

Way number 1: Semi parametric nested array.

This method incorporates a nested array into a curtain panel family.¬† This requires you to manually control the height and width of the panels in order to get the arrays correct.¬† Recommend doing types so you can “Select all instances” if needed.¬† A quick rundown of this method (and the usual video!).¬† This does require you to have previous knowledge of nesting.

1. Create Louver extrusion for nesting
   
2. Nest Louver into curtain panel family and array it
   
3. Load panel into project and create a curtain wall from it.
   

Way number 2: Curtain Wall for panel replacement.

This method basically creates a curtain wall family made of mullions that have a louver profile and no curtain panels.  You then nest this louver wall into another curtain wall as the panels.  This is a simpler method but not as flexible when it comes to vertical louver spacing.  A quick rundown of this method (and ensuing video!).

1. Create louver profile mullion.
   
   
2. Create curtain wall type using Louvre Mullion Profile for horizontal mullion types
   
3. Replace curtain panel in second curtain wall type with louver wall type.
   

I used method one to screate the screen shown in this rendering:

Hope this has helped someone out there and as usual, please comment and enjoy!
