Havent had a chance to read through those links yet (will do that now) but this is my latest attempt. I think that while the blocking is getting closer to what it should be, there are still a lot of...

I will give that a go, but I am still trying to figure out why I got those weird results I mention earlier.

There is nothing i this area so i figure it has to be an artifact of the mesh. And its...

Hi diamondx, I agree with FAR that your blocking is not that bad for 3D wings that are a straight extrude but for wings are swept and tapered the blocking around the tip needs more work to keep it...

Does anyone know how I can make the mesh around the leading edge more square so it all flows together nicely? Or is it always going to do that because of the way its blocked?...
