Breakout Section views have a 'starting point' and direction. The 'Base Point' is that starting point. If you toggle ON the 'Cut Through Model' option then the point will only be used to help define the origin for the 'extrude' vector but the section cut will go completely through the model. Is you toggle the option OFF, the section cut will only START at that point and then go through only that part of the model in the direction of the 'extrude' vector.
