Thickness in Karamba3D model

Hi GH Forum

I’m currently creating a joint in GH and am about to make a Karamba3D shell model of it to make a FE Analysis. However, the thickness of the shell is applied in Karamba3D which makes it difficult for me to construct it precisely as I’m only using surfaces with no thickness. So my question is: Should I create the trickness in the GH model itself and then take it into consideration when I create the Karamba3D model somehow later, or should I create it with no thickness and only create the geometry in the centerlines and then add the appropriate thickness in the Karamba3D process?
