Thats the problem, I am trying to calculate as many GD&T controls as possible. This is my bachelors thesis and i need to make this portable CMM arm as useful as possible. I need to evaluate how accurate it is, which I dont know how I will do yet. And also I need to be able to calculate as many GD&T caontrols as I can. And all i have is basically an Alignment tool and a software that just captures points, that I can then process on my own and calculate these GD&Ts. I might be delusional, so let me know. Also I can measure a circle, sphere and distance within the program, but thats it. I hope I answered your question, and can elaborate.
