I designed a quad copter case and am hoping to 3d print it.  To that end I have a wireframe of the shape I want and I am trying to stretch a surface between multiple plines which are not closed and each are on different planes.  None of the commands seem to do what I need.  Anyone have any ideas?BTW, here is a link to the case file itself:https://drive.google.com/file/d/0B1icptHaGVuvQUhKN1Rrbjk5N2M/view?usp=sharing

Have you tried the LOFT command?
