Hello;

     Wondering why I can't revolve this profile. I checked the profile, & it doesn't seem to be open any where. To me it also doesn't seem to be

sefl intersecting or intersecting the center line. I have some various construction lines in it, but that's never been a problem before. I'd like to spin the entire

figure around the main center line.

Thanks for any input in advance;
