WebDatums reading order can be considered in a manner similar to assembly constraints in a CAD program (e.g. Mates). The difference is, that in a CAD program, the constraint works on a pair of perfect elements (one plane in relation to another…) and a datum reference system links a physical, imperfect element (surface, for example) to a high ... WebNov 26, 2024 · Here, the datum is the surface we need to imitate and the angle is set to 0°. There are 2 types of parallelism: surface parallelism and axis parallelism. We can choose an axis or a surface as a reference. This becomes our datum and we reference it in the 3rd block of the feature control frame as the datum for the feature.
