The primary objective of an engineering drawing is to communicate the drawing information clearly to the user. From our basic engineering drawing knowledge, we can represent the details of an object fairly well through an orthographic projection drawing, indicating the dimension, shape, and size of the object. The invisible features of the object are conventionally depicted by means of hidden lines in their projected views. Sometimes, the internal features of an object are ...
