MESH from rhino to MASS in revit with family instance by geometry node

Hi everyone, I need to bring many geometries from rhino to mass in revit. First I bring it as POLYSURFACES in rhino, but it is too big and dynamo crashes. Then I decided to bring it as MESH.

I tried but It comes to revit as a imported thing, not as mass.
Then I tried Direct.Shape.By.Geometry and It comes as mass, but with too many edges and it is not what I want.
Then, now, I’m trying to import it with Family.Instance.By.Geometry, from spring package, but it does not accept MESH as input, just solid.

Does somebody know how to convert mesh to solid or make mesh work in this node??
