how to turn a Brep into a Surface?

I Extrude curves in Rhino, but when I tried to reference it into Grasshopper, it indicates the Extrude surface isn't a surface but a Brep, anyone knows how to change it into a Surface in Grasshopper?

    A BRep is the equivalent of a polysurface.

    If you [Explode] your BRep it should give you the constituent surfaces.

      A polyline, or a polycurve (a curve with non-continuous segments) would always generate a Brep/polysurface on extrusion, not a surface. So either you deal with them as multiple surfaces for each curve as Taz suggested, or you make your curves in a way so that there are no tangential discontinuities.
