Min dimension in View
Min dimension in View
(OP)
Hello,
Question about Min dimension in view.
On the drawing there are two concentric diameters shown in a cross section view. There is a Min dimension between the two diameters. The Min does not state ALL Around.
How would I know if the MIN is specified at that particular location or if it is interpreted to be anywhere between the two diameters?

RE: Min dimension in View
One of the diameters has a diametral callout (right?) and the MIN dimension is controlling the wall thickness between the two features. This is often done on tubes to control the wall, but is toleranced, and the all around is obvious, but I would ask, what is the max? Is another dimension controlling that?
RE: Min dimension in View
I would have thought it straight forward as well. The diameters have diameter symbols.
The view is not a wall thickness. It is two stepped internal diameters (similar to a counterbored hole). The min is shown in a section between the two steps. I was using the min to control the location of the holes in lieu of using a positional geometric.
I am told that the min applies just where I placed it and it is not checked all around. I was hoping to find something in one of the ASME specs which states when dimensions are all around vs just in the view.
Thank you for your input.

Pararaph 1.4(m) seems to apply to your situation.
Question: Why not use a positional tolerance FCF on the features? Seems like a better (and normal) way to specify the features.
