Roof on load bearing walls (CLT panels) Karamba analysis

Hello, I am a Student trying to learn Karamba and i wanted to analyse a simple roof structure carried by load bearing walls. However there are multible issues i am encountering:

  1. How should i mesh the roof and the load bearing walls together so i can still seperate them later? I used Mesh Brep (Karamba) and fed all surfaces in there and used create surface element (karamba) and gave them there the Identifieres A and B. however i am not sure if it worked because i put in so many surfaces. And i dont know how to check it…
  2. out of some reason i do also not get a legend and the space in rhino turns red or black when i click on the shell and model view component but i do not know where i went wrong:(
  3. I am also not sure if karamba notices that the standing surfaces and the roof surface are intersecting…

Here is a picture of the structure:

and here is my grasshoper code:

It might just be very basic issues that i am encountering but i would be very happy if somebody could look at it…

THANK YOU!

you can control your data by using by following the example below. then you can make sure that your meshes are actually connected.

However there are some fundamental things you need to take care of:

  • units - I believe you are working in cm so set your model to cm
  • make sure to flatten your inputs in the AssembleModel component, as the dashed wires mean you have multiple lists which means also multiple models
