First-Year Engineering Program Orthographic Views as a  Communication Tool As in all Engineering Drawings, the key is  communication from the person creating the  drawing to the person reading it. An orthographic representation of an object is  unique, unlike a pictorial presentation.  Thus it's  used to provide accurate information about the  location and size of features. Reading orthographic drawings by visualizing the  3-D object becomes a real skill that is valued out in  industry.

First-Year Engineering Program Which Views to Present? General Guidelines Pick as Front View the view that describes the  most features. Most common combination of views is to use:   Front, Top, and Right Side View. Any other view different from the Principal Views is  called Auxiliary View (see 3.15 in the Technical  Graphics text).

First-Year Engineering Program Glass-Box Approach - Introduction Most powerful technique to understand  orthographic projections. Suspend the object with transparent strings  inside a glass box. Freeze the view from each direction (each of  the six sides of the box) and unfold the box. Animation  illustrates glass-box approach.
