True position tolerance to a face
True position tolerance to a face
(OP)
Hello folks
First time on this forum, so I hope I'm in the right place.
OK, my question-
We have shiny new designer in the company, who is producing drawings with faces toleranced by true position back to other datums/planes. I'm perfectly familiar with true position of holes, but I've never come across this style of tolerancing a face. I don't understand how a face can be toleranced in this way, am I thick, or is my new designer nuts?
I hope that makes sense.
Cheers

RE: True position tolerance to a face
There are applications this kind of makes sense, for instance centering a notch/open slot on an width.
However, I'm not sure this is what you mean.
Can you post a sketch or something illustrating your point.

Position tolerances do not just go on round holes. On a flat feature, they would apply in one direction only, and you would not apply the diameter symbol.
Almost certainly, a profile tolerance would be more appropriate for a flat face of a part.
