How to hide topography mesh edges

Hi, I have modeled a topography in SU, modified in Rhino and imported back to SU via .skp. I can’t seem to hide the terrain mesh edges, meaning all the triangulation edge lines. I have tried the smooth, view hidden geometry and changing the style to hide profiles, nothing. Is there something out there, maybe a plug-in? I just want to see a plain green field with no triangulations.

The mesh has a strange format that is making all the faces individuals. Exploding it will help.

Have you noticed that Rhino can export directly to SketchUp? No need to go through .obj or any other old file format.

My bad, I did export from Rhino as SKP (SU can’t import OBJ)
