Thank you for the reply Odysseas.
One more epic Grasshopper project of yours.
You truly justify your name!

Thanks.

Yes, you just reference all the curves which correspond to the vertical elements and the floor envelope and it calculates the rest. I guess you can set up some rules for optimisation in grasshopper but you'll first have to define your lateral stiffness limits for the size of the columns/walls as well as the vertical load resistance demands. This example is based in tweaking the pre-sized columns in order to satisfy the torsional sensitivity demand of EN1998.

Very nice!
Do you manually need to assign the load bearing walls/columns?
