Abstract: The invention relates to a method of analyzing an assembly of parts with respect to at least one predetermined design criterion, characterized in that it comprises the following steps performed on the basis of the design data represented by digital mock-ups each reliably representing a part in three dimensions, the assembly of mock-ups together defining the assembly of parts in three dimensions:—identifying the parts of the assembly,—determining, among the parts thus identified of the assembly, several first pairs of parts which each define two parts in mechanical contact with one another,—determining, among the first pairs of parts, several second pairs of parts which each define two parts which conform to said at least one predetermined criterion,—identifying a set of second pairs of parts,—as a function of the set thus identified, determining the result of the analysis of the assembly of parts with respect to said at least one predetermined design criterion.
