In geometric dimensioning and tolerancing, the true position control frame defines the true geometric location of a feature relative to what?

Explanation:
True position is defined inside a datum reference frame created from datum features. This frame provides a fixed coordinate system anchored to the part, so the true geometric location of a feature is specified relative to those datum references. In other words, the feature’s position is measured with respect to the datums, not to material properties, surface finish, or temperature. Material properties describe the material, surface finish relates to texture, and temperature affects dimensional stability; none of these establish the reference frame for locating a feature.
