Hi all.

Back to my RC fuselage.  Thinking of doing a different skin for the outer fuselage.  So I draw outside of the Lofted surface already created previously.  The guide curve is a pain but I managed to move it so that the lofter surface can be seen.

Great.  Added the first guide curves on the front and no problem.  As soon as I added the second guide curve that's more complex, it pukes on me with this error, "Rebuild Errors, the guide curve #2 is invalid.  It cannot be converted to b-spline form.  Not sure I understand what the error is and how to fix it.  Any suggestion?
