If you need to reset the protractor tool...
Use the ESC key to exit the tool.
A good anchor point is typically a ridge, eave or a spot on a roof surface where you can easily place the tool to go perpendicular to the tilt of the roof.
You want to make sure that you are careful to notice when the blue line fades into the roof. You want to go just above that point to get the most accurate roof pitch measurement using the protractor tool.
For roof planes with no ridge, you can also measure the tilt using the eave.
