Lofting problems

[charlescooke58]

Can somebody please explain why I get this every time I try to loft the other half, what is line not smooth and how do I rectify it.

You need to attach your model so the Forum users can take a look at it.

That red dot means what it says.  At that location the two sketch articles are not tangent connected.  To do that tip, will need Loft Surfaces. 

You could Loft surfaces top and bottom, Spar top curve to Trailing Edge, with rib and tip curves as rails, or visa versa, but when  using body edges will give you tangency control.  same for lower surface.

Might help....

thanks I added the file hope it works.

Loft tool is so finicky, non connections like these are trouble finding somewhere to land.  Leading edge doesn't reach the wing, and the Trailing edge overlaps.

Might help....

I would consider re-designing this completely from scratch.

The yellow icons in the time indicate warnings that should all be fixed before you continue.

Perhaps, before starting to design an airplane, do a couple of simpler projects to get down the basics, e.g. proper sketches, and then progress to a more complex design.
