Hi again,

I am trying to generate a rib by using an intersection plane. When I zoom in after doing the intersection, it appears that the intersection was not completely accurate, and the resulting curve is somewhat taller than the original part (see the attached images and file). I don't think it is just a display issue, because creating a planar surface out of the intersection and then re-intersecting that surface with the original part again results in some additional curves that weren't there in the original intersection. Is this a tolerance issue, and is there any way to fix it? The difference is small enough that I wouldn't normally worry about it, but it can make later work a pain because there end up being multiple snap points that should really line up on top of each other.
