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 ...

WebDec 9, 2024 · Since we are denoting true position in the feature control frame, we will denote it using its assigned symbol of the crosshair (⌖) in the geometric characteristic symbol block. Selecting datums. We start with selecting our reference datum plane. We can use a minimum of one datum. Datums could be points, lines, or planes. WebUnderstanding Datums. A clear reference is necessary for specifying a target’s orientation tolerance, location tolerance, and profile tolerance —that clear reference is the datum. A datum is a theoretical, ideal feature such as plane, line, or point, which does not actually exist: this makes it difficult to understand.

WebJan 26, 2024 · Circular runout requires a datum, unlike circularity. So remember to mention the datum on your callout. Circular runout is always understood as a 360° rotation around the datum axis and hence, is used without a diameter symbol in the feature control frame. Runout is a surface control and not a feature of size control. WebMay 20, 2009 · Datum targets are designed to contact parts at specific points, lines, and areas.
