How to Create a Merge Shape in Flash
You can create two basic objects types in Flash, Drawing Objects and Merge Shapes. Merge Shapes are unique in that you can select the line, fill or both.
Using the Selection tool click on a Merge Shape line to select just that line. Double-click the line to select all object lines. Click once on the fill to select the fill. Double-click the fill to select the fill and all the lines.
Merge Shapes work very well with Shape Tweens and as Masks. To create a Merge Shape, you need to set the Object Drawing icon to Merge Shape. For more information on Drawing Objects see topic, Drawing Object.
Click the Rectangle tool (r key).
Click the Object Drawing icon (j key). It has two states, medium-gray and off-white. It should be in the off-white state. The medium-gray state creates a Drawing Object.
Add a rectangular object with a stroke and a fill to the workspace. The new object is a Merge Shape. Try selecting the object lines and fill as described above.
