Claim 0:
1. A computer-implemented method for segmenting a 3D modeled object representing a mechanical assembly, the method comprising:
obtaining the 3D modeled object;
inputting a representation of the 3D modeled object to an abstraction neural network, the abstraction neural network outputting a first set of first primitives fitting the 3D modeled object, the first set consisting of a first number of first primitives; and
determining, from the first set, one or more second sets each of respective second primitives, each second set consisting of a respective second number of respective second primitives, the second number being lower than the first number, the determining including:
initializing a third set of third primitives as the first set;
performing one or more iterations each comprising:
obtaining the third set of third primitives,
merging one or more subsets of third primitives together each into one respective single fourth primitive, thereby obtaining a fourth set of fourth primitives consisting of each single fourth primitive and each non-merged third primitive, and
setting the third set of a next iteration as the fourth set of a current iteration; and

setting the one or more second sets as one or more obtained fourth sets.
