WebJan 19, 2012 · Few months back I saw a tip on profile of a line with datum referred. The drawing uses profile of a line with datum A to control the line elements of the surface , also the line elements are located to the datum A with basic dimension. Since each line elements are located by basic dimension to datum A, the entire surface of the part is controlled. WebAlso, you should always consider how a part will be dimensioned prior to defining the datums. Datum B, the Secondary Datum, is perpendicular to the Primary Datum and sets the orientation of the second axis. Datum C, the Tertiary Datum, is perpendicular to the other datums and fixes the degrees of freedom of the part.
