Tangency between mirrored surfaces

Hi mcdrury,

""""""""""""I was then working on the wing root and was wondering if the model attached is correctly modeled as per BurrMann's comments regarding tangency at the mirror point? I'm not sure I really understood what was being said, but my interpretation is attached (root.3dm). """""""""""""

Yes it is correct. The 3 points you have in alignment there at the leading edge create a tangent connection between the surfaces.

You have them relatively "close" to each other, which will make the connection "look harder" on the surface.

If you delete those 2 closest to the center point, then use the next 2 back and align them with the leading edge, you will see a much more gradual, smooth curve of the surface..

If you are looking in the front view, as soon as you move either of those 2 points left or right in the view, you will have a "hard edge" or a seam there...
