Curtain Walls - ACA vs Revit

[scgillin.182228]

I am by no means an expert in curtain walls in either application but I am brand new to curtain walls in Revit.

So my question is:

In ACA you could have multiple rule based grids in a curtain wall system in order to reduce the amount of custom or unique instances, of mullions or spandrels, etc. on the curtain wall system.In Revit it seems that you can have only 1 horizontal grid and only 1 vertical grid based on rules for that specific curtain wall type. For any grids that don't fall into that specific rule you must use the grid tool to manually place all grid lines graphically. Which is nice because you can see what you are actually doing but it does not apply those lines to the curtain wall type and so for every floor level, for example, you would have to manually place the same lines.

Am I missing something? Is this in fact the case? Am I just not thinking out of the box enough and maybe I should be looking at nested curtain walls etc.

Thanks for your help.

In Revit you could use curtain wall type as type for panel of more complex curtain wall (nesting curtain wall as panel into primary curtain wall), thus creating rather compex spacing of grids from types (of both curtain walls). Hope this helps.

I usually create my own curtain panels that include all the horizontal mullions for each floor. my curtain wall types are the horizontal spacing I want and the floor to floor heights. This makes it pretty easy to create repetitive patterns of vision and spandrel glass or whatever else you want. I have to assume less grid lines and mullions in the model helps performance a little, but I'm not sure about that.

Thanks for the replies. The nested families or panels are seem to be the way to go. I need to work on my family/parametric modeling abilities a little bit but I imagine you can make some pretty interesting and complex walls this way.
I have been using Revit for a while now but this is the first time I get to dive deep into curtain walls in Revit.
Thanks Again.
