The images produced by plane cuts through such structures are polygonal complexes. The problem of finding the edges, when only the vertices of a given polygonal complex are known, is considered. A combinatorial optimization model is proposed whose solution yields an approximation of the complex. The problem itself is solved using simulated annealing. Encouraging first experiments are presented.text::journal::journal article::research article
