Does anybody know if Hexagon offers a (more or less) programming class to learn to use expressions? I've been wanting to get started on these, and reading through the core files. I can think of several ways at least that they can be used here. Locally there is a metrology shop that offers a four hour course, but I took Java in college and as I recall programming isn't something you pick up in four hours.
i still wasnt exactly sure why this was a variable but it occurred to me over the weekend.
you guys setup your posts. take hits on the posts. test part on the posts and see where it isn't contacting the primary datum. add shims. input value of shims to variable expression in order to calculate where the datum is?
Why are you making it so complicated?
Measure the posts, check the difference to nominal, shim to nominal, remeasure the posts, make sure they all measure ±.001 from nominal, load part with datum A contacting the post (the part is large and flimsy so it will lay on the posts), pick up datums B and C which are on the part, measure the part.
