Hello, I am currently working on a parametric facade in archicad and grasshopper and the idea is that the curtain wall panels are a sheet metal which have a grid of circular perforations, and the parametric aspect is that i would like to add an attractor point/curve that makes the holes larger or smaller. I am wondering if it is possible for GH to take an existing curtain wall from archicad, extract from it only the panels and replace them with ones that can be adjusted by this attractor point script, and then also sync back to archicad in the same position. How would i go about achieving this effect? Would it be better to try and build the curtain wall in GH from scratch, or even to just make the panels entirely separate? I saw some videos achieving similar things but not much info on the archicad-GH curtain wall object.

The Archicad-Grasshopper connection cannot modify geometry that it did not create. So, any geometry you bring into Rhino-Grasshopper from Archicad with the relevant components can only serve as a reference geometry, based on which you will need to create your Curtain Wall with the attractor point affecting its panels.
