sat to 3dm conversion is a matter of export of solid 3D models between SAT and 3DM formats, from 3D ACIS to 3D NURBS format.
It might be difficult to find a software that will give you the option to perform such conversion directly, so what many users do, is that they use exchange forma to transfer the designs between different software. Alternatively, you can use one of the available 3D converters for this task.
