Hi rado, see this previous post for some scripts you can set on a keyboard shortcut to make an isometric or dimetric view:

Also if you want to experiment with different angles of your choosing, the settings you can tweak for that are under Options > View. Set the "3D view projection" to be Parallel, and then push the "3D view angles" button to get a dialog that will allow you to enter in specific angles for the view direction:
