Indian Architecture has a strong love towards Jalli wall designs. Even Islamic architecture uses a lot of repetitive pattern. Many architects across ask how to create a jalli walls in different softwares. The issue is, most of the tools are either simply a non parametric modelling tool or non BIM. It makes it hard to create design iterations. 

What is really interesting in Archicad is that, the multi use curtain wall comes handy in these situations. I am showing the simplest solutions to all the designers out there this one use case. Such a wonderful tool. You have a parametric model, quantities and visualization at the same time.
