Upside-down Alignment

Hey guys. I'm trying to do an iterative alignment on a fixture but I'm hitting a speed bump and I'm not sure whats causing it. The points for the manual alignment are identical to the automatic alignment and share all the same properties. The manual alignment shows the vector correctly but the probe is upside down. The automatic one shows the vector correctly and the probe in the correct orientation. I've posted the code below as well as attached a picture of the "upside down probe". Does anyone see where the issue lies? When I run it, I go through the manual alignment and then when it attempts to measure the Master tooling ball on its own, it tries to go to the centre of the tooling ball and reads an unexpected probe hit. Running PC-DMIS 3.7 MR3

  • So I changed the automove to NO and that fixed the issue. Thanks JM for the tip! I'll remember that for next time.

    Ron, this is definitely the correct CAD model. The workplane is Z- so in this case the vector is 0,0,-1 for the tooling balls. If I make a random point on a flat surface of the part the auto vector is 0,0,-1.

    I'd like to say thanks to everyone for the replies and the input. It was all great advice for troubleshooting that I'll keep in mind for the future. I'm still relatively new to this so I appreciate the help. All the replies were positive which felt great. I've read a few threads that weren't nearly as polite

    Thanks again everyone,
