One question for a Beginner

[BernardUnlimited]

How do you rotate an object facing exacty up, like not having it tilted. Like after i rotate something and i try to rotate it to face upward so i put it on the z axis but its still tilted, what do u have to do?

If you hold down the CTRL key while rotating, you will see that movements are constrained to steps of 5°, I think it is.
