Cross Section | Meaning| Definition |Types of Cross ...

Cross section means the representation of the intersection of an object by a plane along its axis. A cross-section is a shape that is yielded from a solid (eg. cone, cylinder, sphere) when cut by a plane. For example, a cylinder-shaped object is cut by a plane parallel to its base; then the resultant cross-section will be a circle. So, there has been an intersection of the object.
