This example shows how to change the color of the selected assembly component.

 

'----------------------------------------------------

'

' Preconditions:

'       (1) Assembly is open.

'       (2) A component is selected.

'

' Postconditions:

'       (1) Color of selected component is changed to blue.

'       (2) Selection set is cleared.
