AB A part definition drawing must accurately assume the functional requirements of the mechanicalsystem to which it belongs to enable correct functional dimensioning. This dimensioning is essentialfor the methods office to define its production and for metrology to define its verification.In this paper, we adopt a method that uses a 3D model of a mechanical system. It is thereforenecessary to provide the nominal models of the components. Also relies on analysing thepositioning of each part in the possible working states of the mechanical system.The part functional dimensioning requires mastery of the ISO-GPS language (mainly UNE-EN ISO1101:2017 and UNE-EN ISO 5459:2024) and a precise analysis of the operation and positioning of eachcomponent.Analysis of how the mechanism works must be based on the tolerance stackups, applying the ‘worstcase’ and statistical methods, depending on the number of components integrating the chain ofdimensionsThe positioning of each part depends on the identification and definition of the contact surfacesand on the order of the prevalence between them. This analysis of the part positioning will allow thedefinition of the necessary datum systems and the definition of the initial GPS specifications ofdimension, tolerance zone and pattern (maximum or minimum material condition).Both analyses should provide us with the ISO-GPS functional dimensions in the functionaldefinition drawings according to ISO 16792:2021 and other GPS standards.
