New in Rhino 6
The Rhino 6 development process started with the overriding goal to remove as many of your workflow bottlenecks as possible, in addition to making thousands of large and small improvements. That meant making Rhino faster and able to handle much larger models and project teams.
Thanks to thousands of pre‑release users, we were able to field test and refine Rhino 6, making it the fastest and most stable version ever.
