just dreaming: will It be possible sometime to encript grashopper definition into revit/inventor parametrical families?

Hi Massimiliano, the thread above should help with instructions,  Basically if you type the rhino command sdrZZLicenseRequest If it's not clear let me know and I will help.

Hey Guys, I downloaded the geometry gym but it keeps asking me for some command sdrZZLicenseRequest to activate most of the tools. I am currently working in Rhino 4,0 and grasshopper 8,0003. Do you know what can I do?

Many thanks Jon.
Now everything functions what I need!

Hi Rafi,

I found yesterday some (but not all) components had issues with GHv.0.8.0002 and 3, so I uploaded new builds of most today (If I've not uploaded one you need, let me know, the rest will be tomorrow).

I've also changed the location the plugins are loaded from (normally an issue for Windows64 bit users). If you already have todays versions and still have problems, please send me an email with a description of the error and I'll help resolve it.

Hello Jon,
I have the problem that all components SSI are deactivated and redly.
Possibly does not function your components on the Neusten Grasshopper version yet or the Licenz file does not.
Do you have an idea?
