Sometimes it is necessary to save data for creating a mesh (its vertices and polygon indices arrays) to text, for example, for further use in a script or addon.

We can export the mesh to one of the open formats, for example, to *.obj, but if we need only its vertexes and polygons data, we can use the following simple script:

Here we set the file name for saving data, make two arrays with vertexes and polygons data and save them to the specified file.
