so you arriving BOYSE, then select radial 41 and fly hdg 245, and you'll know you at VALES then you cross radial41 of ML VOR. At that time you should be at 30 miles from ML VOR, and so on.

The most important part is to arrive to BOYSE. Simplest  way to do that, to arrive at radial 50 of ML VOR. So you'll know you at BOYSE then you at 45 miles from ML VOR\DME. the rest is pretty simple :)

all calculations not precise here. They'll just to give you idea of how to fly RNAVs.

MOST IMPORTANT, if you using maps without marker North\South - CHECK IT USING ANGLE TOOL. On pic above - North isnt up!!! its not hard to find 0-180 line on map like this using indicated headings (like BOYSE - VALES 245 deg)
