The image in Fig. 5 shows the tyre as a greyed out background ready to have the wheel sketch added.

It is not necessary to change the workplane for the wheel, as the sketch will again be rotated about a sketch.

 

 

 

 

 

Right click on the base workplane menu option and select new sketch. Accept the default name of sketch1, and draw the axis of rotation line as shown in Fig. 6

Right click again on the base workplane menu option and select new sketch. Once again accept the default name of sketch2.

This sketch will form the sketch profile for the wheel.

The actual profile sketch for the wheel does not have to be exactly as shown. The profile of the wheel can be changed to match the design produced by the user.

However it is important to ensure that each end of the sketch representing the axle are the same size.

 

Fig. 7 shows an example wheel profile with the dimensions which are important to the subsequent design of the rest of the undercarriage model.
