There are a few new parametric modeling plugins for Rhino; this is the first video I have seen that shows how they actually work. I’m pleasantly surprised with how Ledas has been able to pull off the UI in Rhino. Elegant job by just selecting objects and using the command line to type the distance, angle, etc. Then they have their feature-tree/object properties on the right.

Thank you for this short review, Matthew
The only thing I’d like to add to it is that the Constraint Manager (on the right, but it can also be attached to the left) differs from traditional feature-tree. We manage constraints, not features. Constraints are all independent (no order), features usually form some dependency (tree-like order) – this is an important difference that allows constraint-based approach to solve quite sophisticated parametric problems that cannot be expressed in traditional feature-based modeling systems.
Thanks for the clarification, Dmitry. I need to try out this software. Nice work.
I find this video both tiny and very hard to make out what’s happening. I downloaded it from You tube in 720 and I really can’t get any kind of idea how this program works because the video is so small and so blurry.
