Need alignment explained

I'm new and I am having a hard time grasping how to set alignment on a part. If I have a block sitting in front of me. My x goes right and left, y, away and towards me and my z up and down. I would click on alignment and choose plane, line, point? Then the software prompts me to take a plane. If I take hits on the top of the block as a plane, level to it in the z plus. Then my line, do I take a line on top from left to right or do I take the points of the line on the plane in front of me (y plane?) Then what, I am lost when it comes to rotation. If I take it on top of the part from left to right, is that xplus direction rotated around zplus? Where does the point need to be taken and why? Very lost. I'm a pretty smart guy, can read a print but have no experience with PC Dmis and very little with GD&T. Is there a website or good book I can reference? lol

Thanks,

  • Thanks for everyone's help but back in November we had a union lay off and I was the lowest senior man in inspection..so, I am back to building machines and no longer using the Romer Arm. It's sad and funny, the arm has been sitting ever since and probably won't be used again until I get recalled back to the inspection department. This should happen in a couple years after some of my older counterparts retire.
