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...

Things 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.

karamba replied to Lukas G's discussion Intersectiom Joints in the group Karamba
"Hi Lukas, you could use short springs to connect the beams of the different layers: choose the translational stiffness very large to come close to a rigid connection, select small values for the bending stiffness (e.g. 0.1 kNm/rad). Best, Clemens"

karamba replied to Kendrick Tay's discussion Glulam Simulation in the group Karamba
"Hi Kendrick, at the moment (version 1.2.2) there is this limitation for the transverse shear stiffness you mention. In version 1.3.0 this limitation will be lifted. The shear stiffness influences the results only in case of very compact…"

karamba replied to Balazs Kisfali's discussion Angular steel cross sections to cross section table in the group Karamba
"Hi Balazs, you can use the principal values of the moment of inertia of the cross sections to specify them. In Karamba the calculation will not be exact in case of loads which produce shear, since currently (version 1.2.2) Karamba assumes that the…"
