I'm using QGIS 2.18 and wondering if there's a fairly simple way to create a symbol with an arrow on the end of a ray, and an arc in between.
The thing that makes it complex is that the angle is not consistent. Also, I always want the arc to travel from the first line drawn to the second line drawn so I can show angles greater than 180. In my drawing point 1 is the left most arrow, point 2 the center, and point three the other arrow. So the arc would travel from line 1-2 to 2-3.
