Made some good progress thanks to all the suggestions. Got the wing section sorted out by using the foil coordinates to create an image and then building a MoI section over the image using Freeform>Control Points.



Sorry, have more questions though!

I can't seem to shell out the attached solid? I've used Offset>Shell and also Offset>Inset and the function fails to make any changes. Any ideas?



I can carve out a piece using Boolean>Merge with a down-scaled copy of the model-solid, but would like to find out what I'm doing wrong with 'Shell'.



Also the Fillet>Fillet function does not seem to work for the junction of the fin and fuselage base (not that I'm too worried). I selected the seam and and started with a fillet of 0.1mm but no go, also any ideas on this?

Cheers.
