5. Open the Front Wheel Assembly in its own window and switch to the ConfigurationManager. Add a configuration called Small Tires, and change the tire to the configuration called Small Tires, which has already been created.

6. Switch back to the main assembly window (Ctrl+Tab), RMB+click the Front Wheel Assembly in the FeatureManager, and select Component Properties. Select the Small Tires configuration for the Front Wheel assembly, as shown in Figure 8.14.

7. Repeat Steps 4 to 6 for the Rear Wheel assembly.

8. Double-click another configuration from the list and watch the assembly change from small to fat tires.

9. Change to the Motion configuration. RMB+click the Stem-Fork assembly, select Component Properties, and set the assembly to be solved as Flexible.

10. Exit the dialog box and check to see that the fork linkage mechanism moves by dragging the fork. Notice that the fork works but that the front wheel does not move with it. The bike design is not yet complete, so you do not need to worry about that at this point. Putting the front wheel in the fork assembly could be used to make the wheel move with the fork.

11. Switch to the Skeleton Driven Positions configuration.

12. Display the assembly layout sketch at the top of the FeatureManager.

13. Create two new derived configurations under the Skeleton Driven Positions configuration, one called Default Position and the other called Compressed Position.

14. Activate the Default Position configuration, and make a coincident mate between the Top plane of the Chainstay part and the sketch line indicated in Figure 8.15. Again, the wheel does not move at this time.

15. Activate the Compressed Position configuration and make a coincident mate between the same plane and the line that is angled up at 10 degrees.

Note

For these configurations, you also need to set the Advanced options just as you set the top-level configurations in Step 3. If you do not do this, you may need to suppress the unwanted mates manually in the appropriate configurations.

16. Switch to the Mate Driven Position configuration. Change the stem-fork assembly to a flexible subassembly (RMB+click and choose Component Properties⇒Solve as Flexible).

17. Add new derived configurations called 1, 2, and 3. While creating the new configurations, ensure that the Suppress new features and mates and Suppress new components options are selected. Leave the 1 configuration activated.

18. Make an angle mate between the Bike assembly Top plane and the face of the link, as shown in Figure 8.16.

Using angles to position the fork

19. Once the mate is complete, double-click the angle dimension (you may have to double-click the angle mate to get it to display and then zoom out to see it), and change the value to 18 degrees. Again, with the change, the fork may fly to an unexpected location. Pressing Ctrl+Q brings it back.

20. Switch to the configuration 2, unsuppress the angle mate that you made in Step 18, and change the value to 25 degrees. You may have to change the con-figuration 2 to Flexible, although it should inherit this property from the parent configuration.

Note

You need to set the Fork assembly to solve as Flexible for each configuration. You may also need to control the alignment for the angle mate manually for each configuration.

Summary

Display states in the assembly can save you a lot of time because they change faster than configurations and offer more options for visualization, including mixed display modes. Assembly design tables can select display states and drive many other parameters in assemblies. Remember also that Modify Configurations and the Configuration Publisher work in assemblies as well as in parts. Assembly configurations are a very powerful tool for product
