This object will be modelled on the basis of the TTRS concept and vector modelling synthesised by the metric tensor of a sheaf of vectors. The first problem that we propose to solve therefore is the formal expression of these relations. After that, the dependency will be analysed and illustrated considering a 3D object. Keywords: Geometric Perturbation, Metric Tensor, Geometrical Specification. 1. INTRODUCTION ISO dimensioning and tolerancing standards for mechanical parts are not geometric specification standards but st...
