Converting Mesh Cloud .stl file to solid model using scan to 3D

Hi all.  I've recently started trying to create solid geometry from a mesh cloud file.  The file is in .stl format and was generated by a 3d scanner.  I'm really struggeling to create solid geometry from the mesh cloud using scan to 3d.

The mesh prep wizzard is fine, but from there the curve and surface wizzard dont yield any usable results.

I was hoping someone here could download the file, convert it to a solid and direct me how (more or less )

The file can be found at

I'd really appreciate any help, vids, tuts, models you guys can give.

Thanks,

Duane le Roux
