Hi I'm a new user of GD&T and recently I got confused about a partner's drawing and I would like to propose some change.
However, I got no confidence about my proposed change.
I googled a lot about positional tolerance trying to find some explanation of similar case.
But, all the posts explained positions of cylindrical holes and use surface as datum A, B, C.
I rarely see the introduction about the positional tolerance for the mid-plane of a square or rectangular hole/rectangular blocks.
I put a few question in the attachment, appreciate if anyone could help clarify and explain them.
Thanks a lot!
