How do I create a scalloped edge - SketchUp - SketchUp Community

I have SketchUp Make 2016 installed on Windows 10 and I’m trying to add a scalloped edge to a board. In the above image I want the “D” option, e.g. sine wave. My board is 96" long and 11" wide. The sine wave should repeat about every 12" and the distance between the max high and max low is 2" on the bottom edge. As in the image of sample edges I need to start and end on the max low point on the ends of the board. Scalloped Board.skp (18.1 KB) BTW I need the instructions for dummies.
