Computational Error if Points close together

I have some data points that I am giving to mfc sample 11_Plate to fit a surface and display. The first point is at 0,0,0. The second point is at 0,0,6.1e-14. The Plate sample gets OCC Computational Error unless I delete one of the first two points. What is the minimal seperation between points to avoid this error? Why isn't OCC protected from this type of problem which could easily occur?

we are using a tolerance of Precision::Confusion() to decide if we consider two points to be the same and remove one of them.
