Use karamba on existing shapes/surfaces

Hi, first post! I’m an architecture student from UCL. I wanted to know if I could use Karamba on an existing shell to measure high tension points, so I know I should add more or less material - trying to create an efficient structure. Is there a YouTube tutorial anyone knows of, as I’ve only found tutorials that create the shapes in karamba.

Essentially the OptimiseCrosSections component does this, but you can also set this iteratively by analyse a starting shell and then changing the cross section according to your input values
