I found one thread similar to this. but it really did not answer my question.
Here is the situation.
We use a punch with specific decimal hose sizes like 0.39" and 0.261"
I have to make sure the flat patterns of sheet metal that use those holes have exactly that size. Not any other close common fractional size. In this way exported flat patterns going through nesting software match the punch tooling.
Also I want to use those holes on a pattern for patterning bolts down stream in assembly. So I want to use an actual hole, not a cut.
What is the right kind of hole selection for this? The hole wants to show up as 25/64 not 0.261
