.rfa is a Revit Family file extension
This is pretty straight forward.
First create your curtain wall system and define the mullions you want to use as the louvres for the horizontal grid, I typically set a mullion size to 10x200 (you can also use custom profiles)
Set the spacing you want (i.e. max 200mm)
Draw your curtain wall, if you defined vertical mullions for the borders, you will need to select them in your view, unpin and delete.
I would attache some images if I knew how to on this forum!
Hi Moldin, I'm sure this is possible (there's a lot of expert modellers online here ;)
Can you confirm are you using Autodesk Revit or ArchiCAD/
Thanks,
