Extrude or projection

Hello again! I need help or advice. projecte lines in my model, but at the time of extrude if I get the address but not a solid. Could you tell me how I can extrude this. Another way I can think of is to extrude and then make that piece adapt to the solid. I attach photos of my project.


Hello - you can split the faces of that object with the curves and then ExtrudeSrf or OffsetSrf > Solid=Yes - you’ll need to do some cleanup however - removing the back faces of the results and joining things up.
