Short edges

[micheus]

Micheus ... ACROSS does not mean across the long way ... or across the short way. It just means ACROSS. That's all. My video is in fact plane cutting across the thin faces.

yeah, you were right. That was a second situation that I didn't pay attention before.

I also could repeat it and I noticed another thing here: if I look very close those edges were the cut should have connected the new vertices it's almost impossible to select some edge depending of the camera orientation - it's necessary go away a little to be able to do that again.

Stem, I don't fell like I could do the right change to the try_connect_1 code I had mentioned in the post #6 because it is part of the wings' core and I don't want bring back any old problem as dgud has mentioned. But, I can investigate the Plane Cut code and see what I can do about it.

By now, if you lay in this situation I would suggest you to work with selection lists and move the unconnected vertices a little (use an edge as axis); connect them and move them back. It's a horrible workaround but it will work.
