WebDatum Reference Frame: A three-dimensional Cartesian coordinate system that defines the product. Dimensions and tolerances all originate from the DRF. Fully Constrained: When fully constrained, the part to be evaluated is completely immobilized: all degrees of freedom of the part are locked. An engineering datum used in geometric dimensioning and tolerancing is a feature on an object used to create a reference system for measurement. In engineering and drafting, a datum is a reference point, surface, or axis on an object against which measurements are made. These are then referred to by one or more 'datum references' which indicate … re4 devil may cry mod
