9-slicing symbols

1. Double click the symbol or button to enter symbol-editing mode.

2. In the Properties panel, select Enable for 9-slice Scaling Guides.

3. Move the guides and place them appropriately on the button or symbol. Make sure that the parts of the symbol that you don't want to be distorted when scaling (for example the corners) are outside the guides.

   

   9-slice scaling guides positioned so that corners aren’t distorted when the button is resized.

   
   

4. (Optional) Lock the guides: In the Properties panel, select Lock for 9-slice scaling guides.

5. To return to the containing page, click the page icon at the top of the document panel .

6. Resize the symbol as needed by using the Scale tool .

   

   The button scales without distorting corner shape.

   
   
   After applying 9-slice guides to a symbol, you can nest it in the protected regions of other 9-sliced symbols, creating complex objects that scale perfectly.

If you plan to scale an object in only one dimension, you can use three slices instead of nine.

 Complete the standard 9-slice procedure, but in step 3 do one of the following:

• For vertical scaling, drag the horizontal slicing guides to the edge of the object.

• For horizontal scaling, drag the vertical guides to the edge.

 In the Document Library panel, double-click a symbol icon to enter symbol-editing mode, and look for slicing guides.
