Alternative Skeleton Models for Larger Assemblies

Industrial Design Concept Design Detailed Design

The idea of a more collaborative effort between concepts and detailed design that would allow for

ptimization

simultaneously is possible using this approach.

TARDEC Amphibious Combat Vehicle (ACV) Skeleton Model This is the top skeleton model for the TARDEC Amphibious Combat Vehicle Hull Survivability Demonstrator. This skeleton will drive all the individual parts

shape. This

skeleton controls thousands of features.

Concept Skeleton Model (Upper Hull) This is the upper hull skeleton that is simplistic geometry that can be easily

modified. This is

a model that can be made by Advanced Concepts and transitioned to Detailed Design.
