# Wheel Fixer

For your wheels to rotate and turn correctly, AVC expects that your models pivot points are located in the center of the geometry. This, however, is not always the case and isn't always possible to fix in the 3D. 

Since v1.9, AVC comes with a tool to automatically fix the local positions of the parent GameObjects so that everything rotates correctly.

In the image above, you can see the pivot point for the wheel is incorrectly located at 0,0,0 of the entire model. This pivot point is what the wheel will rotate around when the vehicle is moving, to make the wheels spin, resulting in an incorrect rotation, displayed in the clip below.

### Using the Wheel Fixer window

Before getting started with the Wheel Fixer window, make sure to follow the '[Preparing Your Vehicle](/vehicles/preparing-your-vehicle.md)' setup, otherwise the fixer won't work.\
\
1- Open the window by going to Tools -> e23 -> Wheel Fixer.\
2- Select the parent GameObjects for the wheels that need fixing, and drag them on the 'Wheel Parents' array in the fixer window.

3- Click the 'Fix Wheel(s)' button.\
4- The console will show logs when complete (almost instantly), then check your wheels rotations.
