Simple wheel placement question

Hey, I just started using GMod and am trying to make a basic vehicle. Is there a way to easily line up wheels on rounded objects so that they’re symmetrical? Would this require an addon, or is there a hotkey to do this in normal GMod?

there is a great addon called smartsnap, which shows a grid on the props and you can enable/disable it in the Q menu under the options tab and if u press E near one of the grid points it will point right to it so you can place a wheel on the corners perfectly

there u go, if u have any questions PM me
