How to setup a machine path that cuts using the 4th 180 degree rotary axis that rotates on the x-axis?

Hi, 

I am using fusion 360 to create machining paths to cut shutter-ply extracted from a 3d model. Each piece has a unique shape and generally has various angles cut along the edges, we are fitting these pieces together to build the walls of a climbing gym. We have been using 2D and 3D tool paths to cut the boards, but we have a CNC that can rotate 180 degrees on the x-axis and we are not sure how to set up cutting an angle using the rotary-axis. 

Please help with suggestions on how to set up the 4th-axis using the swarf function to only allow rotation along the 4th-axis? 

Thanks in advance.
