:)

yes, thanks for your links; great stuffs.

Actually, I mean such a cad based software which capable for parametric design on a high level of complexity. On the other hand If you do not use one of these you are not an architect :) nowadays, To tell the truth I really not so passionate of these crazy forms, stuffs but there are many of situation when could be very useful. So that's why I would like to take a decision and avoid time wasting. I just getting confused between Grashopper and Generative Components.
