Which Extension to eliminate unnecessary facets?

Hello Forum,
I received some detailed 3d models (stl) from a client to render, but with tons of faces. This causes problems in my renderings-software. With “soften edges” inside SketchUp I don´t get a properly mesh. So - which extension could I use?

Thanks in advance!

Thanks a lot mihai.s! :+1:
It worked!

Even if CleanUp made the model look ok, I would reimport the STL and choose the merge coplanar faces option. That might immediately look ok, or at least give CleanUp less things to fix.

And if the scale is very small, I would suggest using a larger import unit.

Thanks a lot Guys!
