I would like to thank GS for making a very smart move with the Grasshopper-AC connection!!
Let each company, or software, be the best in its field and have a fruitful communication with the others.
That was surely a very clever way of handling the need for parametric.
Better than Dynamo for Revit which I guess will continue to be painful underpowered version of Grasshopper.
Now I'll be hoping for a way to link GDL object parameters with Grasshopper.
