I use Linux Mint. I get sent .skf files that I need to open. I don’t need to work on them, just to look at them. What are my options please ?
What are .skf files? SketchUp files are .skp.
If you want to open .skp files, you could use SketchUp Free in an internet browser.
Apologies ! .skp
or the free SketchUp Viewer f. Windows in connection with either Wine or VirtualBox/Windows.
