Hi Lewis,

re: System like that could fix it in MOI also - right ?

It could fix some things and break other things - it's not good for example for a curve in MoI to have several points of the curve stacked right on top of each other. That's a type of degenerate curve condition which will also cause problems with different calculations.

The difference with something like LightWave is that it's working with a mesh object and the structure of the mesh involves simple connections between just 2 points, in a mesh structure like that when 2 points collapse together you can just implicitly delete the edge that was between t hem, there isn't really the same concept of a long continuous entity made out of a longer series of points like a NURBS curve is in MoI...

Maybe some kind of process like that type of curve welding could be possible in the future I guess, but it can be difficult to apply polygon mesh editing type tools onto curves, they just operate fairly differently.
