For a rectangular solid object with spherical radiuses on all corners, and edge radiuses on all edges, I have decided that the proper callouts are:
4X SR.XXX on the top face
4X SR.XXX on the bottom face
4X R.XXX on the front face
4X R.XXX on a side face
The other 4 edge radiuses are...

Enjoy!
I admit that I can think of no reason not to have SR corners, but if there is no instruction to do it, and if $100K of parts are made and finished without SR corners, guess who eats the pointy-soft cornered parts?
Thanks EWH, but no sir! Assuming the same radius dimension on each edge, radiusing each of 3 edges leading to a corner will NOT cause the corner to be fully rounded! The "shank diameter" of the radius cutter must follow the radius of the third edge radius while cutting the first and second in...
Thanks Heckler,
Yes, I am aware of the callout, but suspect whether it is on to use.
I am trying to dimension "ball corners". In the view where it is appropriate to call out the radius domension, it is not appropriate to call out the all around function. Is there a "ball" or spherical...
I am seeking the proper, complete, and unambiguous method to call out a radius on a corner.
I currently show a radius leader in each view with a radius arc. (example cross-section view)
I have a chassis which I would like to radius on 3 edges coming to a corner. I realized that the individual...
Thanks again,
drawoh,
That is the conclusion I had come to also, but still some issues. The slot is radiused also, so I guess I should do 4x the straight segment, and 4x the raduises, or should I say all around, or can I use an "all around" circle on a dimension?
Thanks ewh and drawoh.
My "problem" is that my continuous slot is in a way, 2 separate features.
Imagine a plane with a rectangular projection. Now imagine a rectangular slot around the base of the projection. That is what I have, a radiused rectangular slot. As it is continuous, it has 2...
Thanks drawoh,
Can I use a single positional for the slot such as in figs. 5-14, or 5-43 of ANSI 1994, or is that only usable in ref. to a centerline?
Can the GDT parallel symbol be used for one side rel. to the other without a datum ref?
or
Can flatness be used for one side rel. to the...

" Dimensions with +/- tolerances are a part of GD&T, and are described explicitly in ASME Y14.5M-1994. If that is what you want, that is what you should call up."
True enough. My issue with that is that my drawing is dimensioned with basic ordinate dimensions. If I were to...
Yes, that was my thought also, but in the interest of using only GDT on the part, I wonder if there is a proper way to do it.
What if I DID wish to closely control the location of the slot feature? Could I GDT it without using centerline?
Hello all!
I wish to GDT a continuous (looped) slot, below a surface, which does not need special (tight) control on its location, but mostly needs control of the width independent of location.
Is there a control for one wall of the slot relative to the other, when neither wall is a datum...
