I have a matrix done but I don’t want to extrude the lines because it goes in one direction and leave a gap.
Can you add a screenshot for me to understand what are you trying to achieve?
it ends up a bit chappy and not union if I use the command extrude curve @tay.othman
Beautiful work. For the infill panels. I’d use edgesrf command below
You can create a surface using the lines from your structure. Then if you want to make them solids (for union) unit first to join the surfaces using the “join” command.
