' This program will walk an assembly structure. For each component it will:
' Assign physical materials to the bodies in the components.
' This program changes the displayed part instead of simply changing the work part.
' Changing displayed part is slower than just changing work part, but it is safer. If you
' have mixed unit parts (english / metric) then the program will error when trying to change
' work parts.
