Multi-Level Assembly

Multi-Level assemblies can be defined as the assemblies consisting of at least one or more sub-assemblies within main assembly.

In the previous chapters, we have seen how to implement top-down design for single-level assemblies. But now we will see the different approaches for implementing top-down design to multi-level assemblies.

We will explore following two approaches for the multi-level assemblies

1. Single skeleton
2. Multiple skeletons
   

EXERCISE 1

The topics covered are as follows.

• How to implement top-down design to a multi-level assembly by using single skeleton for whole project
• Investigating External References in parts at different levels
• Understanding the pros and cons of copying references from the skeleton (located in main assembly) to the parts in the sub-assembly.

EXERCISE 2

The topics covered are as follows.

• How to implement top-down design to a multi-level assembly by using a separate skeleton at each assembly level.
• Creating skeletons in sub-assemblies
• Communicating the design information from skeleton to skeleton
• Communicating the design information from skeleton to components
• Deciding either to define features in main skeleton or sub-assembly skeleton
• Investigating External References in parts at different levels
