Thanks again thomas for your advices. I'm reading Roman's blog articles, and start having a clearer idea on shape definition (topology vs geometry). Feel free to add any other valuable documents. In particular, it would be interesting to have docuents (diagrams or whatever) explaining OCC modules relationships and why not integrate externals module like salomegeom/smesh. For instance I found this one http://www.opencascade.org/occ/overview/ but I don't consider it very informative(as one have to guess relationship by oneself)... Anyway, I think I start to understand how things are organized : The core object is the TopoDS_Shape class, and then there are in on hand geometrical/topological algorithms to modify/create them and in the other hand viewers to visualize them. Is this right? I guess things are more complex than that. friendly, Loïc
