This is just an example I made up to see if my understanding of datums with position tolerances is correct. Let's say I have a pin hole that is located relative to datums A, B, C with a tolerance of .002" - no problems there. Now let's say I want to locate two threaded holes relative to the position of the pin hole with a position tolerance of .002". What I am showing in my example is my attempt of saying "these threaded holes are perpendicular to A and relative to the pin hole with a tolerance of .002" AND perpendicular to A and parallel to B with a tolerance of .002"." I know I could do a simultaneous requirement for these but this was more done as an exercise for my personal understanding (still learning this stuff). Any comments are most welcome and a big thank you in advance.
