Views of Objects


Views of objects

  • GOALS: After this chapter you should be able to:

  • Explain different views of an object

  • Explain how an object can be revolved to illustrate different views.

  • Explain how the idea of a “glass box” can be used to explain views.

  • Be able to identify the necessary views of a given object that is to be drawn.

  • Identify typical objects that usually require only two views.

  • Be able to sketch three or more views

  • Be able to place the views correctly on the page.


Views of objects

  • Every Object is subject to laws of nature.

  • We live in a three dimensional world.

  • Therefore there are three essential dimensions that must be represented in a mechanical drawing:

  • Width

  • Height

  • Depth


Views of objects

  • The front view shows what two dimensions?

  • Width and height

  • The right side view shows what two dimensions?

  • Height and Depth

  • The top shows what two dimensions?

  • Width and the depth


Views of objects

  • Refer to figure 7-5 in your text. The Glass Box.

  • Hidden Lines: Used to show hidden parts (edges). Drawn with a dashed (hidden) line.

The edge would not be visible in the right side view so we use a hidden line to show it is there.


Views of objects

  • The Right Side, Front and Top views are known as “the Three Standard Views.”

  • In circular drawings we use center lines to indicate roundness.

  • Sometimes only two views are required.


Views of objects

  • One of the worst things you can do is draw a view out of place.

  • Always use this orientation:

TOP

FRONT

RIGHT SIDE


Views of objects

  • Line up your views.

  • Use construction lines for measuring.

  • Use a 45 degree angle to project measurements from top to right side view.
