Hi Jacob, right now the end of your wing has a planar end cap on it here:



Before you try to blend it you want to delete that end cap so that the edge you are blending only belongs to a single surface, the wing surface and is not also attached at the same time to the planar end cap surface.

If you blend an edge that is attached to 2 surfaces it's basically random which surface it will decide to be smooth to, and it can easily decide to be smooth that planar cap instead of to your wing.

Once you delete the cap and make the edge only belong to the wing and not attached to anything else it will then avoid that possibility.

So that's one thing anyway, but also in order to get a good blend you would not want to have quite such a distinct upwards traveling shape on the wing - that will make the blend also try to go upwards when it comes off of the wing.

Instead of blend maybe pushing the pieces through each other, then doing boolean union, then doing a fillet might be easier.

Also the front part of your wing is not smooth, it's got a slight crease in it where the upper and lower pieces come together - that's going to make edge-based filleting more difficult because there will be a little gap that it will have to try to fill between fillet pieces there.

So getting that piece to be actually smooth in the front would most likely help.

Thanks for pointing out the crease! I completely missed it.

During my tests I cut off the wing a good distance away from the body and tried to blend that, but it wouldn't work as well - the crease might have something to do with it.

I'll try tomorrow and report the results.

Thanks,

Jacob.
