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.

You need to be a member of Chameleon to add comments!

Hi Ethan

What type of parameters are you trying to update? Chameleon only appears to be able to update text/string parameters. So for most Revit families this is the 'Mark' value. If you want to be able to update a Revit length parameter for example, you need to create a dummy shared parameter first which is text based for Chameleon to update, and then use BIMlink (or Dynamo) to copy these values into the actual length parameter for the family via a schedule.

Remember also that if you want to update multiple parameters simultaneous, the 'Params' input in Grasshopper needs to be flattened.

Hi chameleon group! I'm trying to update parameters with chameleon and even though I have data going into the P0 on the AC component it doesn't give me the option to choose a parameter to affect in the revit side of things... any ideas would be helpful thanks

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!

So, finally I got to instal Chameleon in both Grasshopper and Revit but when I try to run it it promps this message: "Waiting for Revit to connect... Please activate the Place Adaptive Components in Revit" and it gets blocked... What I am I doing wrong?
