The intrinsic direction of geometric feature,the representation method and calculation rules of DOF of geometric feature were proposed.The intrinsic direction of geometric feature was de-termined based on the geometric characteristics and position relations among toleranced geometry fea-ture and datum geometry feature.According to the geometric measurement principles,the computa-tion method of constraint capability of datum feature to the DOF of target feature was proposed,and the calculation rules of constrained DOF of toleranced features were proposed by datum reference frames.The tolerance specification validation method were proposed according to the relationship a-mong tolerance type and geometry of the datum and target entity ,and the correctness and complete-ness validation rules were discussed against the dimensioning and tolerancing standards and against good practice rules in industries.
