Can't see object on scene view

Hello, I’m newbie so it’s probably a stupid question but I can’t see object on scene view. It’s imported from my friend, and he has no issues on his computer. Also when I add another object like cube I can see it perfectly. If it’s something important I actually don’t have mesh renderer, my friend pointed this out to me, but I don’t know how to add it?

You do indeed need a mesh renderer. Just click on your object, then in the inspector click and search for mesh renderer.
