There is also one additional clipping plane available for "cutting" only the mesh (by keeping entire elements), in 'Tools->Options->Mesh->Cut Plane'. -* 5.14 What is the signification of rho, eta and gamma metrics in +* 5.14 What is the signification of Rho, Eta and Gamma in Tools->Statistics? They measure the quality of the tetrahedra in a mesh: -rho ~ min_edge_length / max_edge_length -eta ~ volume^(2/3) / sum_edge_length^2 -gamma ~ volume / sum_face_area / max_edge_length +Rho ~ min_edge_length / max_edge_length +Eta ~ volume^(2/3) / sum_edge_length^2 +Gamma ~ volume / sum_face_area / max_edge_length For the exact definitions, look at Mesh/Element.cpp and Mesh/Simplex.cpp.
