As I understand it, the assembly in question is composed of several parts, which would allow for repeating datums on the drawing (as poor of a practice as that may be). Perhaps if the standard were worded differently, not allowing repeating datums on a drawing, this …

I've just encountered a profile feature data frame on the part i'm checking where the primary datum is on a completely different part. It's my opinion this is wrong and that all datums should exist on the part itself. However, i'm not 100% sure about this. Tags: None.
WebFigure 3. The same figure as Figure 3, without the part itself. The tolerance zones (profile and position – in red) are defined with respect to datum reference frame (DRF – at the bottom-left corner) through basic dimensions. The Datum reference system itself is formed by the intersection of three datum planes A-B-C (in blue). Weba specific, defined version of a 3D system; references against which we measure all other locations; different datums specify different coordinate systems; the version of the datum is important; differences between families of datums change through time; tell us the latitudes and longitudes of features on an ellipsoid; an established standard from which all other …
The image below shows 3 datums – A,B,C. You can see that the primary datum A would lock Y, u and w. Then B would lock Z and X. Finally C would lock the last rotation DOF (v). It would be just as if you had a all surface datums using the 3-2-1 rule. Ver mais A datum is theoretical exact plane, axis or point location that GD&T or dimensional tolerances are referenced to. You can think of them as an … Ver mais The datum features on a drawing are denoted with a series of capital letters. These letters are in boxes and tied to the datum feature with a … Ver mais A datum feature is usually an important functional surface where all other dimensions need to be in spec with reference to it.

These tolerances are described in detail in ASME Y14.5-2009. Many of these 14 tolerances have features similar to each other in the way they control a part’s shape and dimensions, therefore it is important to understand what is the intended …
