[MWForum]Calling mathcats: geometry help please

[Jeff Knope]

Daniel,

Thank you for the explanation of your procedure. I think I'm getting it.

You said, "The maximum value for setpos is 9999." My point is your procedure
is purely mathmatical. There are not setpos operations used, at least not to
the intersections (recall I substitiuted show for the setpos you had at the
end). Since it's just number crunching, would it still reach an "out of
bounds" value?

I really appreciate all your help with this.

--Jeff
