algorithmic modeling for Rhino




Chameleon is a plugin for both Grasshopper and Revit with a focus on interoperability, simulation, and efficient practice workflows. Chameleon’s main advantage is its ability to facilitate easy transfer of geometric data between Grasshopper and Autodesk Revit, but also includes other valuable tools to make life easier, both in Grasshopper and Revit.

Hi Hiroshi

I too have had warnings from my web browser not to download the software as it could be harmful to my computer.

To Hiroshi Jacobs:

Hello, my name is Matthew Reeves. Thank you for creating the Chameleon plug-in. I visited your site to try the plug-in, but was prompted that your site contained malware. I am uncertain what that may mean? Please let me know, for I would enjoy to learn about Chameleon.

I'd like to use Chameleon but Google says your website contains Malware! I bypassed that, but then Chrome blocked the download of Chameleon. Do you know why my browser is scared of your site?

Hello everyone! 

I'm new to Chameleon and I got some nasty issiues. My Revit freezes when Grasshopper finally send the geometry. I found on the Internet that it has something to do with a NUMBER PARAMETER in an Adaptive component family but I don't understand what at all. Can anyone pleas help me and tell me how to make it work finally ? 

I'm currently working on a few projects in my college (architecture) and it would be so mch easier to make a good project with Chameleon ;) so please anyone ;) many thanks to all for your help! 

Al the best!

Have you checked if your files is blocked. Right click on them and check if they are blocked. I had similar problem and that worked by unblocking them.
