What happens when you try to place a fourth waypoint using the Measurement Toolkit?

When using the Measurement Toolkit, attempting to place a fourth waypoint results in receiving an error message. This is because the system is designed to limit the number of waypoints to three for effective operation. By keeping the waypoint restriction to a maximum of three, the toolkit ensures that navigation remains efficient and manageable.

If users were allowed to add more than three waypoints without any notification, it could lead to confusion or errors in path calculations as the program would need to handle more data than it is designed for. This limitation is in place to maintain clarity and functionality within the tool, allowing users to focus on the three existing markers without the system becoming overloaded or compromised.
