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.

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?

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.

Also, I run the installer for Revit and I don´t get the Chamaleon components under the Add-ins tab in Revit. 

Comment by owe on October 18, 2013 at 6:12am

Hi, I have just installed Chamaleon but I only get the interopelability set of commands, not the simulation one and the Utilities ones.

Hi Hiroshi

I am facing some problem with gbxml import component, i am on gh build 0.9.0014. "Input string was not in correct format". 

Is it a version problem ?
