I've never seen this type of callout

[d.evans]

Please help me determine what to do with this.
IMG included. What is this called? Is is a "projected radius"? Any help would be appreciated.

[george frick]

yes- basic radii. there should be a profile callout to locate & define them.

Where is the rest of the call out. True position or Profile and the Projected height? I have seen project call outs but not on a Radius.
If the Radius is theoretically projected to a certian height or distance it should still be in tolerance.

Is this a machined detail?

here's the whole drawing



Sorry for not posting this the first time.

hey my friend. we always have the discussion when we're dealing with gd&t as to whether we interpret or decipher the print. what is the designer's intent? i believe that the (2) basic radii is to be maintained w/in the .010 profile tolerance w/in the entire surface of the pocket. i am guessing (read deciphering) that is why they added "projected" to the basic dimensions of the radii. the profile also reads "all around". actually this is a pretty clear print to me. hope this helps.

George is correct.

Another odd one (for me at least)

Does someone have any info on this callout?
Thank you for any help

It looks like a bad callout.

It looks like a bad callout.

dph51, am guessing you are not referring to the callout as in nodding head and sayin' "man, that is one BAD callout!"
i would concur. perhaps convince the engineer to drop the diametrical. it would then seemingly make a bit more sense.....

Thank you. The feature is a 17.5 mm hole
