Is the print correct?

[greenimi]

1.) Am I right saying this print is not correct?
Missing basic dimension for the positional callout.


"7.2.1.1 Dimensions for True Position.
Dimensions
used to locate true position shall be basic and defined in
accordance with para. 2.1.1.2."


2.) If they have used perpendicularity instead of position I guess would be okay.

Just please confirm.



Thank you

Without the diameter symbols, you have to indicate the direction of the tolerance zone. You also have to specify what happens in both directions, not just one.

Thank you guys for your great input.
I have revised the sketch per your latest comments (to have it for reference on future posts/readings).

The only thing, that might get in the way of using your advice (and change the actual print) is that now we need 2 gages to verify the positional requirements.--one to qualify Ø.030 and one to verify Ø.005.

Again, thank you for your guidance. Nice we have this place where we can learn from each other this "language" and apply GD&T in a correct and unambiguous way.

If you really want a gage it mught be one gage with removable parts.
