_MeshIntersect
intersecting those 2 meshes gives 2 curves - not 1 as expected.
even after welding the vertices at a seam - this problem is not solved.
the resulting 2 curves do have a gab of 0.1 (document tolerance 0.001) at the dot (x).
tested both tolerances
auto and literal (why isn t this called document-tolerance ?)

hi @Tom_P my guess is that this happens because you are intersecting right at the vertices. Maybe @piac can confirm this and comment if there is anything that can be done about it.
In V8 this is fixed apparently
tested in WIP / Beta / V8

(Mac Intel)
moving up the diagonal mesh once by 0.001 i get 3 curves
moving up a second time 0.001 I get one curve as expected…
so for sure it has something to do with tolerances - but maybe also some special cases the algorithm does not care about / handel.
