How to convert from Catia 3D data to OBJ format?

Hello all,

Is there any way to convert from part design or GSD surfaces to subdivision meshes?

A customer asked me that whether it is possible to export from Catia files to obj format or not.

I found a way to export the shape made of subdivision meshes to OBJ in IMA(Imagine & shape) , but I don't know how to convert and export the shape made in part design(body) or GSD surfaces to subdivision.

As far as I checked, only subdivision meshes can be exported to obj from IMA.


Does anyone know how to do it? Is it impossible?

(Sorry for same question from 3DS CATIA Community)
