Interpenetrating solids

What is intersection of solid?

Intersection of Solids. INTERPENETRATION OF SOLIDS. WHEN ONE SOLID PENETRATES ANOTHER SOLID THEN THEIR SURFACES INTERSECT AND AT THE JUNCTION OF INTERSECTION A TYPICAL CURVE IS FORMED, WHICH REMAINS COMMON TO BOTH SOLIDS.

Let's have a look at a construction of an example:

Let's look at horizontal square prism and vertical square prism.

        Lets look at 2 cylinders interpenetrating one another

            This quick clip is about a Cylinder intersecting with a Cone

    You need to practice by doing more drawings on this topic. See your teacher for clarification and more exercises.
