BIM through GH and Rhino

I am interested in hearing about projects that have been taken through production to construction in Rhino and GH.

Can the bespoke nature of Rhino with GH be promoted as a powerful hybrid system for quality in the BIM game?

I think the couple is simply the best.

Flexible, powerful and intuitive.

Will Rhino 5 users get a free upgrade to 6 (GH integrated)?
