How many views should we draw?

 

When constructing an orthographic projection, we need to include enough views to completely describe the true shape of the part. Simple parts require less views.

 

The standard views are...

 

  • Front
  • Top
  • Right Side

 

The remaining 3 principal views usually do not add any new information.

The Front view

 

The front view shows the most features or characteristics of the object.

  • It usually contains the least amount of hidden lines.
  • The front view is chosen first and the other views are based on the orientation of the front view.

 

View alignment

 

The top and front views are aligned vertically and share the same width dimension.

The front and right side views are aligned horizontally and share the same height dimension.
