To change the shape of an object, such as a polygon or a line, you must add, delete, or move a vertex on the object.

To change the shape of an object:

1. In the Graphics menu, click Edit.
2. Select the object you want to edit.

   The object vertices and the transformation box appear on the selected object.

3. Press the vertex you want to edit and drag it to a new location. When you are satisfied with the new position, release the cursor.
