Import rhino to sketchup

[Anssi]

I imported a file from Rhino into Sketchup Pro and the model look like a wireframe not solid

How? Did you export a SKP file from Rhino or use some other intermediary file format?
In Rhino, if you are dealing with curved objects, I would convert the surfaces to meshes and then use the mesh reducing command before saving as SketchUp. Otherwise it tends to create a mesh that is impractically dense for SketchUp.
