Hello Michael,

It looks to me as though you've cracked it !

I am afraid that I am going to expose my ignorance here - did you intersect the wing and fuselage surfaces and then apply various fillets ?

I confess that I am struggling to understand how you achieved your result.

The "sliver" you pointed out was an attempt by me to fill the the original gap I discovered, between the upper and lower wing surfaces. I am still puzzled as to how I created the gap in the first place.

Is there any sort of "history" file created within your software that would allow me to review previous actions ?

John
