AutoCad - Create Multi-Arrow Leaders (2004/2005/2006/2007)
It's common to need leaders that point to more than one location. AutoCAD doesn't offer an automatic method, but this quick technique is almost as good. Start by creating the leader as usual by choosing Dimension | Leader and following the prompts. Then select the leader and click the arrowhead's grip. At the stretch grip prompt, use the Copy option. Now simply specify the additional endpoints that you want and press [Enter].
Something strange happens in AutoCAD 2007, though. If the leader ends on an object, when you add new arrows and press Enter, they seem to disappear- However, they're really on top of the original arrow due to their association with the object. You can move them with grip-editing to the desired location.
