could someone please explain to me the way catia arranged the OctreeTriangle Mesh (TR3) mesh structure node/points connections in a .dat file. Because when i imported the same coordinates of the points into catia, and it formed the structure nicely. But when I tried connecting the points like how it is written in the .dat file, the connections do not make sense. The coordinates of each point are usually written on the top part of the file, and the connections on the last part (below the coordinates).
Please if you are still confused, you can create a structure, mesh it with OctreeTriangule Mesh and export it to a dat file.
