How to generate .egads geometry file?

Hello, I am post-doctoral researcher from India. I am working on grid adaptation for hypersonic flows. I am using SU2 for CFD simulations and MMG for mesh adaptation. I need a geometry file in (.egads) format to define the boundary description while performing the adaptation.
Can someone please help me or direct me how to generate .egads file?
I have my current grid file in (.su2, .x, .iges) formats.

Thanks.
