Two positions - one hole (question about drawing)

[Vladimir]

Hi guys !
Faced with a measurement so far incomprehensible to me.
For one and the same hole, two positional measurements are proposed, but with different tolerances. I haven’t seen this before, but before reporting a drawing error, I need to make sure that this is indeed the case. Has anyone seen something similar, or what can be done about it?
If additional information is needed, I will provide it without any problems. 111.jpg

One is to make sure that the hole is positioned correctly. The other is make sure that holes are good to each other. It should have been a composite FCF.

[Vladimir]

I also thought about the composite FCF, but in both dimensions the bases are the same, maybe I don’t understand something...

Not sure that's right this is a rectangular zone to one hole only with two limits perfectly acceptable IF you drop the dia symbol.

[Vladimir]

UKCMM thanks for the help, I will definitely take note !

If the control frames are exactly as drawn then it's an error (or the one with the looser tolerance is redundant).

Is there definitely a Ø sign proceeding the tolerance?

[Vladimir]

yes, there is this Ø sign

[UKCMM]

Then you need to go back to the engineer and explain this is wrong.

Interestingly, this is a drawing of our client, about which we said that only their designers are never mistaken in the drawings

[Vladimir]

I will give a more complete version of my drawing, maybe this will clarify the situation more

This is what the engineer appears to be trying to describe.

[Vladimir]

Excellent! I understood. Apparently, in fact, an error in the drawing with a sign of diameter. Thanks !

[Vladimir]

I create this measurement, but I doubt the settings of my FCF
When I made a composite measurement, it gave 0 in meas in second FCF, so I made two separate ones and this is what happened. but I always doubt everything and this measurement is no exception
I am attaching a version of my drawing in full accordance with the original drawing (changed the purpose of the datums)

You appear to have X and Z selected in the advanced tab only select the axis you need, also not sure why you have a shift in the Z.

Thanks for the amendment! In fact, I did everything wrong. Now everything fell into place. You helped me a lot
