	Abstract:	Currently, algorithms of mechanical part visibility determination are slow, because the part surface is cut into numerous elementary surfaces. In this article, we propose to take into account the visibility properties of convex and concave surface patches, in order to treat the object in a global way. This new method is studied on 2D curves; 3D extension is considered.
	Keywords:	digitalisation; optimisation; part visibility; convex surface patches; concave surface patches; freeform surfaces; form acquisition; product development.
