Set the number of sides of your polygon by double-clicking the Polygon tool in the toolbar to bring up the Polygon settings dialog, where you can change the number of sides of any selected polygon or set the number of sides for polygons. The Polygon settings box includes an entry field for Number of Sides and a field for Star Inset, which is used when you are drawing stars. Holding the shift key while drawing polygon forces all sides to be the same length. For an irregular polygon shape, adjust the polygon after you draw it using the Direct Selection tool. Grab individual anchor points and move them around or use the Convert Direction Point tool, nested under the Pen Tool and accessible with the Shift+C keyboard shortcut. Use it to turn sharp corners into rounded corners. Without a preview, it can take some trial and error to get the star just right, but once you understand how the Star Inset works, it’s easy. With the Polygon tool selected, click on the page to bring up the Polygon settings dialog to specify Number of Sides and Star Inset. Enter a number into the Number of Sides field that corresponds to the number of points you want on your star. Enter a Star Inset percentage that affects the depth or size of the star points. Drag the cursor across the work area. InDesign doubles the number of anchor points in your polygon and moves every other anchor point and toward the center of the shape by the percentage you specify.
