What is the definition of a datum in GD & T?

Definition: 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 anchor for the entire part; where the other features are referenced from. A datum feature is usually an important functional feature that needs to be controlled during measurement as well.

Can a datum be placed at the center of a feature?

No – a datum may never be positioned on the centerline of a feature. Typically a center line is the center of more than one feature, and this would be ambiguous. The datum must be placed in one of the few ways shown in the diagram. Either on the hole, on the Feature control frame, or on an extension/leader line.

Are there any letters that do not have a datum?

Where you have exhausted all letters A through Z, the datums continue from AA, AB, AC etc. The only letters not permitted are I, O and Q. Older revisions of the standard required datums in the following format: – A – This method was discontinued with the 1994 revision of the standard.
