Modeling the wheels

We will now create the first set of wheels for the tank. In the following steps, we will turn the cylinders into complex wheels:

1. In Edit Mode, enlarge the wheel placeholder by selecting it and scaling it by a factor of 5.

Figure 10.8 – Scaling the wheel

2. Create two loop cuts in the cylinder and extrude them inward by pressing Alt + S to create a gap:

3. Extrude a hole at the front of the wheel:

4. Create a hollow circle with 16 edges in the middle of the wheel. Extrude every other edge on this circle and scale them down slightly.
5. To do this, select every other edge, extrude it with E, and snap it back into place with the right mouse button. Then, scale the extruded edges down on two axes towards the middle of the circle:
