#### Surface Point Specific Parameters

Snap: When this option is set to Yes, Snap applies zeros to the less important secondary and tertiary axes values so that the measured result is only in the primary axis. For example, if you are measuring the top surface of a part, you are really only interested in the height of the surface in Z. The X & Y values don’t matter as much and should be pretty much equal to the theoretical values. Due to possible tunneling errors, etc. the X & Y may be off by a little bit.
