How do I resolve this Loft?

jared_ja

Hey everyone. I'm still working my way through using onshape and have run into a bit of an issue. Ive been primarily designing more rigid designs and it was time to design something more organic. So Ive been trying to resolve this loft for a helmet I'm recreating but every time I try and apply more than 3 Guide lines for it the loft fails and instead shows me this red dot. (which i thought indicated that the guide there wasn't intersecting but I could be wrong.. I've checked the lines and to my knowledge all of the points are pierced so I'm not sure what im doing wrong. Any help would be appreciated. If you do manage to find a fix please let me know what you did. Ive shared the link to the file.

The rear profile and bottom profile didn't meet at the back.

I went back in and noticed what you were talking about. But even after i corrected the geometry of the rear profile it still wont resolve. The loft fails as soon as I apply a 3rd guide line and always states the issue is where the sline meets the edge of the bottom profile. Again all of the guides are pierced correctly to my knowledge so im still at a loss

Didnt seem to work. Im still having the same issue after applying a 3rd guide line. Not sure what other issue there is right now. Im beyond my depth at the moment.
