Sheet Metal Axes: T

[Bulldog40]

OK, be kind. I used the search but can't find what I'm looking for. I was wondering if someone had a good definition of what a negative T value and positive T value is? The way I try to explain it seems to get others confused so I feel better off not explaining it.

Hello Bulldog40,

I'm going to attempt to do an attachement for you.

If it doesn't work out, let me know. and I'll email it out to you.

The explanation I use is that when a probe drives to a surface, if the probe hits the surface at the correct point, T=0. If the probe contacts material prior to the theoretic point, T is a positive value. If the probe goes through the theoretic point to contact material, T is a negative value.

When I program to surfaces ( what I do most ) I make sure the surface vector is pointing away from the surface I am inspecting and toward the ruby end of the probe.

Thanks guys. Both of your answers will be very helpful. This is what I was looking for.
