I'm very new to this and working my way thru the tutorials. There is one where you make a little knob with a bore with keyway in the middle of the back of the knob. Everything goes great until I insert the bore from the library. I am not able to align the keyway or center the knob nor align the keyway. I've done it several times and it's kind of random how this ends. Want to be able to insert the bore object with the key aligned to the top of the knob.
