How to ensure probe model in planner is in the correct position? (Stylus system creator/Planner/Simulation question)

[[Lu...]]

Hello! I was recently informed that my company will be investing in planner and simulation so i can make programs while the CMMs are running. To prepare i have been trying to create the probe models off of stylus system creator.

Creating the probe models has gone well so far, but one probe setup i cannot find in the drop down menu and there is no documentation to confirm exactly what it is (the setup was created before i started working here) so i measured it and used the generic setups to create it.

Which leads to my main question, how can i be sure the placement of the styli on the model, is the same as the placement of the actual styli? I'm not very confident in the way i measured it, so I'm expecting it to be a little bit off. How off can it be for planner before it would start to cause issues? Is there a way to measure distances on the probe model, which i could then hard check to ensure it is the right probe setups? 

I have just been going off of measurement and looks in order to find these builds since i have no records from my predecessors on what parts were used, so its likely that i selected the wrong one, and I'm worried that it can mess up programs i create via planner/simulation.

I will likely be asking more questions about planner/simulation once i actually have it in front of me so any advice is appreciated, thank you!
