When you click a main assembly or assembly part in the Assemblies tab or in the Vehicle Drawings Panel, the system displays a button in the Repair Panel with either the letter A to indicate main assembly or B to indicate assembly part and a number to indicate the assembly number for the vehicle model. In the following example, the Repair Panel shows that the main assembly is number 74.

If you used the Assembly tab to select the assembly and you now click the assembly or assembly part button , the system will highlight both the main assembly and any assembly parts in the Vehicle Drawings Panel, as shown below.

Notes:

- If you selected the main assembly or assembly part in the Vehicle Drawings Panel, there is no need to select this button. The system will automatically highlight the main assembly, assembly parts and the assembly button in the Repair Panel.

- In some cases, assemblies are further sub-divided. In addition to the letter B you might also find the letters C and D followed by the assembly number.
