Hi, I have been struggling with this model for ages. It is a type of vacuum cleaner and I am trying to create a filled surface to connect the surface that I have already modeled. I have been trying to create a surface that will work but nothing will.

I am sure that I am asking the software to do something impossible, but I can't tell what it is. Is anybody able to tell me how to fix it? I also need the surfaces to thicken. Sometimes the surfaces don't thicken and I don't understand why

I should add that I have searched the forums already. All I really need is to understand what any error messages mean. Or if no error comes up as well.

Any help would be very appreciated.

Thanks,

Will
