I have done the installation process as directed at http://ardupilot.org/dev/docs/building-ardupilot-with-arduino-windows.html.
Up to apm connection stage to arduino IDE I did not find the contents of Sketchbook according to the image. There are only libraries, modules and Tools. For APMmover2, APMcopter and so on are not visible.
Can anyone provide a solution?
note: i am in a project making a boat survey.
