Transcription: The basic approach to finding the intersection of a plane and a solid is similar to that of two planes. However, to simplify the problem, you must use some principles of virtual intersection, spatial reasoning abilities, and common sense. Identify all lines. It helps to write down a list so that you don't forget to consider any of the lines. Identify the intersection area. Find the intersections or virtual intersections of the solid edges on a plane. You will treat the solid surface as a group of planes. Establish intersections by the physical limits of the objects. Establish visibility.
