Opera - Is it possible to convert modelled geometry/CAD into conductors in Opera?

Hi,

I want to model and analyse a coil in Opera-3D which has a complicated geometry that would take too long to create using the available conductor shapes in Opera. I have a CAD model of it and was hoping it is possible to convert the CAD into a conductor, does anybody know a way of doing this?

Any help or advice is appreciated, thanks.
