Connected Lines

Hi I’m new to Karamba and I’m trying to work on a simpler geometry before I go to the actual geometry I want to analyze. The first question is that there are lines that should be connected to each other which are not connected. I already used the “connected parts” function to see which ones are the problem but I don’t understand how to specify that they are being connected. if I put the shell I have defined into “assemble model” as well, the lines are connected,
but that can’t be the solution.
Thank you in advance. An answer would help me a lot!

hi, your curves are not split at their intersections therefore not connected.
