Converting a 3D surface (stl mesh) into a 3D SketchUp object

Good morning all,

I have an STL file that represents a 3D surface (without thickness). It is a mesh based on triangles (Over 600,000).

This surface should have a flat base of a certain thickness with opaque faces on the sides in order to present the appearance of a solid object without hole.

I want to be able to use this surface in SketchUp 2019 software to apply a wood texture.

Please tell me the different operations to be performed to achieve this result.

Regards,

Do the same for every side.
