About the data - there are different outputs in [Deconstruct] component that will give you data directly. For example for slab it will be structure, building material, composite, thickness, edge angle and so on, and for the Zone there are things like category, name, number, height etc. The problem is that only a small part of those outputs are useful. The useful ones would be height, name or thickness (however I encountered some bugs trying to use the name from the “name” output), but vast majority, like “Building Material”, or “Composite” are closed only for ArchiCAD. You can use them to reuse them recreating some geometry, or creating from scratch but you are not creating “Composite” nor “Building Material”. It’s just picking an item from ArchiCAD library. Being able to use them more easy would greatly improve speed of work. Let’s hope it will happend soon, because pushing Live Connection further is one of the main thing Graphisoft is talking about now regarding newest ArchiCAD. So until then, when we want to use data from “Property Setting” I am afraid that we have to help ourselfes with such scripts.
And about the opening to Grasshopper, you mean something like a tutorial for beginners? Focused on what specifically? I think that as soon as I will find some spare time I could try making something similar.
