Which is the tool for rotating your object? (If you want to check how you modeled it and to fix the edges and details)
Do you mean rotate the view to see more parts of the of the object? It should be the middle mouse button.
But to actually rotate the object, press “r”
MMB, click and hold then drag things around. It works.
or press “R” twice and you can rotate an object in a different way. If you are just modeling though, it is best to leave everything on the axis that it was created. So if i were you, i would just hit numpad “.” to focus on the object and then your view will rotate around the object instead of the other way around.
