Multi-view Drawing Isometric views can be easily and quickly understood.But maybe a number of graphical features are not shown.This happens when a given feature will overlay or partial cover other features which we are trying to show or explain. Isometric views are suitable for representing preliminary ideas or sketches. In real Engineering Practice,Multi-view Drawing is still very important. Shanghai Jiao Tong University 4
