You are responsible to produce a sketched layout from the

provided critical dimensions. You are also required to design the

three boxes. The BOX is used in an outside environment.

Top-Down Assembly Modeling

Top-down assembly is a conceptual method used to develop products from within the

assembly. In Top-down assembly modeling, one or more features of the part are defined

by something in the assembly. Example: A Layout sketch or the geometry of another

part. The design intent of the model, for example the size of the features, location of the

components in the assembly, etc. take place from the top level of the assembly and

translate downward from the assembly to the component.

A few advantages of the Top-down assembly modeling are that design details of all

components are not required and much less rework is required when a design change is

needed. The model requires individual relationships between components. The parts

know how to update themselves based on the way you created them.
