Information on D-Shaft Standard
(OP)
I'm looking for some information on a standard method of dimensioning a d-shaft on a drawing. I've included a picture to show what
i'm calling a D-Shaft. I can't find anything on the web or in my books. Any info would be appreciated. Thanks in advance.

If the flat is not critical to functionality of the shaft you can use less elegant method (in my opinion), that is simply apply two directly toleranced dimensions: 1) for shaft diameter, 2) between flat and the opposite side of the shaft.
Since this looks to be relatively long feature, you may want to condiser control of straightness of derived median line of the shaft as shown in fig. 5-3 (Y14.5-2009).
As a matter of fact you did not write anything about your major functional concern for this application, so please just treat my answer as a suggestion.

It would be used inside of a knob for a stove, or radio possibly.
I could not find anything like it on McMaster-Carr or anywhere on the web.

Flatted shafts would be an alternate search term. Also look in Boker's catalog, they should have smaller od shafts than the 1/4" ones in McMaster.
