Short edges

[Stem]

[Body]Cleanup command has a setting for edge length tolerance, why would that be an issue?

Wings 3D gives me the ability to work to 0.0001, even with constraints, why should working with such distances cause issue?

Of course I can work to different scale, and scale model in export settings, but should that really be needed? I like to work to actual scale.

Another point. If I use different sale (x10), so the shortest edge created will be 0.005(as from example mentioned above), that works fine for "cut", but if using "Plane cut"(so I can set position), the distance of 0.005 is too small for Wings, and the edge will not be created.
