Profile - All faces

[jkb_mcg]

I have a drawing of a small rectangle piece. The length, width and thickness are all 3 basic dimensions with a callout of Surface Profile of .010 to ALL FACES. How would I go about getting this on the CMM?

All points you check will be +/-0.005, that's about all that means. "ALL FACES" is simply a short-cut to put all tol in a single FCF instead of making one for each surface/face of the part.

But how am I to check all these features at one time since its a 2D feature? Just use Vector Points and construct a feature set? I would like to just use calipers and verify the +/- .005 but not sure how to report the actual profile

Don't need to check them all at once, unless you want a single dimension for the entire thing. Single points, all dimensioned at +/-0.005. If you want a single dimension for the report, you can check all the single points, construct a feature set, dimension the feature set. It will be correct as long as each individual point has the correct THEO values.

Any profile is a 3d feature.
Sounds like someone has used a profile tol for planar faces.
Just report flatness and position if they are planar.
If not you need a model to work to to compare a feature set to.

You need to do a 3D best fit to check all surfaces at the same time.

Is this just Profile(form) or Profile to datum(form and location)

Sorry guys...I'm tied up on another problem...I'll keep checking in on this thread. Thanks for all the input so far.

Funny thing is...it doesn't even have any datum callouts. Its just Profile of .010 "All Surfaces"

3D Best Fit, like I said before.
