Im currently doing a tutorial made by Andrew Price from blenderguru. Its about modelling a hand grenade. Im at about 19 minutes where he wants to make the top handle tingy on the grenade. When i want to mirror my plane, the plane doesent mirror. Rather a new plane sticks to the mirrored plane. So when i move the plane around both planes move around in the same location rather than the opposite side of the axes.
Any ideas are appriciated.
