ok, I have fund answer. Points indices are 1-indexed. So need increment all indices with one. More detailed here: https://github.com/IfcOpenShell/IfcOpenShell/issues/955

that is IFC file. I think, I was wrong with something parameters, which use to interpretating coordinates. But wich parameters..

I have convert vertice and triangles of simple cube.. but its some strange here - all coordinates are wrong. points: [[array([0., 0., 0.]), array([1., 0., 0.]), array([0., 0., 1.]), array([1., 0., 1.]), array([0., 1., 0.]), array([1., 1., 0.]), array([0., 1., 1.]), array([1., 1., 1.])], triangles: [(4, 7, 5), (4, 6, 7), (0, 2, 4), (2, 6, 4), (0, 1, 2), (1, 3, 2), (1, 5, 7), (1, 7, 3), (2, 3, 7), (2, 7, 6), (0, 4, 1), (1, 4, 5)]]

Please tell me how you can resolve the issue. In a python program, I have a description of a 3D figure. It is presented in the form of coordinates of points, which are combined into triangles. In fact, these are rectangular objects (walls). For example: Points:(1.,1.,1.),(1.,1.,-1.),(1.,-1.,1.),(1.,-1.,-1.) Triangles: (1,2,3),(4,2,1)[/i] how can i achieve automatic 3D shape formation in ICF format with use ifcopenshell(python)? I understand that I need to add coordinates and triangles. It seems clear...
