ISDX Success?

Is anyone using or know of firms using ISDX for ID surface modeling? I would like to know if it is an efficient tool for creative production and parrallel integration with engineering. How has the value of parametric surfacing streamlined your ID work? Can surfaces be controled easier than alias or rhino? Has anyone invested the time and effort into making a switch from another package and felt that it was a successful move? Any links or images of designs created in ISDX would be helpful!
Please share your experiences.

There has been number of posts about ISDX… just run a search.

I’d be interested in seeing some designs made with ISDX that are superior to just using ASX. Also, can anyone describe or show examples of how they’ve made ISDX more parametric?
