algorithmic modeling for Rhino

About Grasshopper...

For designers who are exploring new shapes using generative algorithms, Grasshopper® is a graphical algorithm editor tightly integrated with Rhino’s 3-D modeling tools. Unlike RhinoScript, Grasshopper requires no knowledge of programming or scripting, but still allows designers to build form generators from the simple to the awe-inspiring.

Rhino WIP for Windows now available

All Rhino 5 for Windows users are invited to Serengeti, where Rhino is developed.

We are inviting current users to try, test, and provide feedback on the work-in-progress (WIP) release while it is still in development.

You will need:

  • 64-bit Windows 7 or above
  • Your Rhino 5 for Windows license key. You can find it here...

Thing to try:

  • Since Grasshopper is included with some enhancements, try your existing GH definitions and plug-ins. They should all work. Let us know if they don't.
  • The ghPython enhancements.

"Nope, you can set the enabled/visible states of all selected components, but there's no way to select components by type. Well, I assume Andrew Heumann can do it with his plugins, but there's no standard method for doing it."
