How can we see the sections obtained by karamba3d as a list?
You can export the cross section table from Karamba to a csv file to get the entire list.
What should be the input of the path?
Do you have an example to better understand?
You do not need to plug a path if you are reading the default cross section library from Karamba. Just these two components work.
You can refer to 3.3.13: Read Cross Section Table from File - Karamba3D 1.3.3
