Mesh line intersecting failing

Hi

I’m trying to run a series of intersections between some lines and a mesh. One of the lines continues to fail because it is perfectly intersecting an edge. If I move the vertical line 0.00000001 in the X or Y axis, the intersection will be found.

However, on a colleague’s PC, the intersection works for them using the same Rhino model and GH definition. So I suspect the issue has something to do with unit tolerances. How can I fix this?

@piac Not sure if the issue has something to do this bug.

Hi Paul, could you check the Rhino versions?
