Can you post the .obj file that you generated for this one?

When you export to .obj, the .obj file does not contain any edge weighting, there is not any facility in the .obj file format itself to store edge weights.

So there is not a way to transfer an edge weighted model using this file format. The .obj file that you generate where the edge weights have been stripped out will not generate your same shape in any application. There isn't a way for the receiving application to automatically know what your edge weights are, they are effectively discarded during the .obj export.
