Problem with pasted cross sections (Loft wont work)?

Hi I'm very new to SW so pls bare with me. I'm trying to produce 3-4 relativley simple kite models, as part of a Hons project. Each with a different 'flat projected area', rectangular, elliptical & triangular. I'd planned on sketching the planform outline, inserting perpendicular planes & pasting on NACA foils (scaled). To get the final curve I was going to use the 'twist' function.

I think my airfoils, even though they look connected are in fact not. Any specific instructions on inserting cross sections (curve through xyz) onto perpendicular planes, to create geometry for a loft would be welcome.

Here's a couple of pics so far...
