For example you ve 1 I created a 12-petal flower polygon and your client wants only 8 petals. You select the edited shape with the Pick tool and then decrease the number of sides using the spin box on the property bar. Stars and Complex Stars You have variations on polygons at the ready in CorelDRAW in the same group as the Polygon tool. The Star tool can be used to create pointy polygons with anywhere from 3 to 500 points. The Complex Star tool creates a number of combined polygons to make a star shape you can create interesting symmetrical shapes by filling a Complex Star the result contains both filled and vacant polygon areas as the component paths intersect one another. Working with the Star Tool The Star tool produces objects by using the click-diagonal drag mouse technique CTRL constrains the shape to symmetry SHIFT lets you drag from the center outward and CTRL SHIFT dragging creates symmetrical stars beginning at the initial click point and traveling outward. On the property bar when the Star tool is chosen you have options for the number of points for the star and the pointiness sharpness of the resulting object how severe the indents are between points. At a setting of 1 the star object becomes pointy not at all you ll see that it looks quite like a Polygon tool object. So if you can make a star using the Polygon tool why would you ever choose the Star tool The answer is because the geometric structure of a star shape is always perfectly symmetrical if you use the Star tool. Although you can use the Shape tool to manually tune the sharpness of a Star tool object s points the angle between points is always consistent. In the next illustration you can see a Star tool object compared with a Polygon tool object that has been clumsily edited. You can t perform this goof with the Star tool its interior angles are always mirrored and symmetrical. Failed attempt
