Hi Kevin, thanks for the image - it is a bit small though and only from one angle.

Since you're trying to very exactly match the profile from different directions, do you have images zoomed in on just the canopy from different directions (like front view, side view, etc..) ?

That would definitely help otherwise it will probably be many more rounds of just trying different shapes that then you'll say are not quite exactly right...

Maybe NURBS is just not a good fit for your project or the way that you like to work.

Trying to do contoured surfaces tends to be a more difficult area since they are not as totally clearly defined by side profiles as a purely mechanical shape. So it is pretty natural that things like aircraft and automobiles are some of the more difficult shapes to work on.
