Vision only alignment?

Vision only alignment?

Hi, I am currently playing with the trial software to assess whether we want to go ahead with purchasing.

I am interested in using ONLY vision tools for this assessment. I cannot for the life of me figure out how to do a basic alignment. Any software I have ever used, I can measure two lines, call one my Y+, the other my X+, and now I have my origin and alignment. Every tool and instruction I'm finding in CMM-Manager relies completely on tactile probing. 

Please tell me I'm wrong and just not finding what I'm looking for. I've tried several things to align just to the corner of a 4" gage block, but no matter what I have tried, my measurement across the block ends up ~.0025" off due to skew. 

Thanks
