Case Study: Complex Assembly Design
The case study for this lesson is a skateboard assembly as shown below. The focus of
this case study is the design of the support component. This support uses references
from a skeleton model to control its overall size and location in the assembly. Publications
are used to control the external references created between product components.

Design Intent
The skateboard assembly must meet the
following design intent requirements:
Component locations must be controlled
from a centralized location.
• Using the skeleton method, component
locations are controlled by referencing
geometry in a skeleton model.
Support geometry must update in all
components.
• Reference geometry and parameters
created in the skeleton model can be linked
to the necessary features. When the
dimensions are changed in the skeleton
model, they will update in all linked
components.
References must be strictly controlled.
• Using published geometry, only published
elements are allowed for selection when
creating external references and assembly
constraints.
