You can imagine Merge Drawing mode in Adobe Flash Professional as a way to draw shapes in a destructive drawing mode. For example, if you draw a circle and overlay a smaller circle on top of it, and then select the smaller circle and move it, the portion of the second circle that overlaid the first circle is removed or cut away.
When a shape drawn with Merge Drawing mode enabled has both a stroke and a fill, they are considered separate graphic elements that can be selected and moved independently.
Shapes on the same layer that were created with the Merge Drawing mode merge together when they overlap. Selecting a shape and moving it results in the overlaid shape being altered.
To enable Merge Drawing mode, follow these steps:
Note: Once objects are drawn, you cannot convert them to the other mode. However, you can group objects (Modify > Group) that were drawn in Merge Drawing mode to make them behave like objects drawn in Object Drawing mode.
To learn more about drawing objects in Merge Drawing mode, see the section titled Drawing modes and graphic objects in the Flash documentation.
