Hello,

Im working in grasshopper with rhino 8, trying to figure out how to utilize compas’ BTLx features. For starters, while some of the compas test files work for me, the btlx one does not. Most of the components are labelled “old” and the error tooltip says “compas.scene module not found”.

I’m wondering if something about my compas installation is wrong - i have installed the compas module for python via the terminal and installed and verified my compas\_timber installation from within grasshopper.

Any pointers would be greatly appreciated, thanks!

Hi @timber ! It does sound like you have an old installation if your components have the “old” label, how did you installed it?

Cheers

Indeed it sounds like an old Rhino7 installation of the COMPAS Timber plugin.

Before proceeding, you might want to remove the old components, otherwise they will keep appearing in Rhino. To do that go to the UserObjects folder and remove the COMPAS Timber .ghuser files.

To get the newest plugin:

1. Start a fresh Rhino8 instance
2. Install COMPAS Timber 1.0.6 via the Rhino Package Manager
3. Restart Rhino8
4. Open a fresh Grasshopper document and drag in the CT: Install component, this may take a minute
5. Remove the Install component

Now you can open any of the example files on our [food4rhino](https://www.food4rhino.com/en/app/compas-timber) page, for example the BTLx from geometry example file. Or directly start using the plugin by dragging in the components you need.
