Thanks Bryan,
I did figure out how to use the clearance plane. It was not turning on and off the autoposition points that hurt me.
I would prefer not to use it, but people more important than me are paranoid about the floor associates leaving the probe head in a crashable place and it became an "or else" situation.
The radial out does sound interesting though. Can I radial out from anyplace on the table to a PP above the fixture?
Thanks!!
Jeff
