All around radius callout
All around radius callout
(OP)
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 callouts would still not mean that the corner was fully rounded.
I am tempted to use the all around symbol, which I am OK with, but the radii do not go around all edges of each surface. Think a cube with the top face fully radiused, and the side faces radiused on their top and vertical edges.
Anyone?

RE: All around radius callout
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 corner callout?

Think about it!
Calling out "all around surface" on any surface, will do the job, but I am seeking a more elegant method or one using symbols rather than text.

Anyone have a better plan?
RE: All around radius callout
You are correct. I was approaching it from a modeling standpoint, where it would normally be the resultant. You could specify "4X SR.XX" in addition to the "6X R.XX" callout and you would be covered.

Give your machinist some credit! If you call out 4X R.XX on the top view (to cover the vertical edges of your cube) and callout R.XX with the "all around" symbol on the front or side view, do you really think your machinist is such a bonehead that he won't understand that you want a SR on the corners and do the verticals first?
Think about it!

But it probably wouldn't hurt to CYA and call out a ref SR (4X SR).
Merry Christmas all!

4X R .XXX or SR .XXX will work, depending on the design.

Here is another from Portugal:

Enjoy!
RE: All around radius callout
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 defined by the SR callouts.
No surface of all around symbols are required for this.
Additionally (on some other parts) I have some SR centers falling outside the part boundary, and near other center marks. For these I have dimensioned the centers, and drawn a dashed circle of equal radius on the SR center.
It looks clear and good and right. I think ANSI should adopt it!
