Engineering Drawing Third Angle Projection

3rd angle projection is a type of orthogonal projection system used to create 2d drawings. Third angle projection is primarily used in the united states and canada where it is the default projection system according to asme standard asme y14 3 2003 and british standard bs 8888 when the 3d object is projected into 2d paper after projected front view the top view is placed on the top and the left view is placed on the left.

Engineering drawing is the language of engineers.. The difference between first angle and third angle projection is the way that a 3d object is rotated on a drawing to show the different sides and views. The third angle projection or first angle projection different countries and regions typically use one method or the other although this can depend on a company s customer. 4 4 views are now positioned as follows.

Since world war 2 where the uk sent engineering drawing to the us for manufacture the uk has adopted 3rd angle projection as the general standard. It is very important that the projection method that was used is indicated on the drawing as it will eliminate any confusion when interpreting how a component or part should be assembled or manufactured. First angle projection and third angle projection.

If you want yourself to be a successful engineer sound knowledge in engineering drawing is a must. Having a good communication skill is one important qualities for a successful career. The difference between first and third angle projection is in the arrangement of views and with reference to the illustration in fig.

View b from the left is placed on the left view c from the right is placed on the right view d from above is placed above view e from below is placed underneath. If one regards the artesian coordinates as being made of quadrants then 1st angle and 3rd angle are two different quadrants in which an object is places and different planes on to which the drawing is projected. In the third angle projection object is placed in the third quadrant and the projection plane lies in between observer and the object.

It is widely used in united state and asian countries. In the first angle projection system the object placed in the first quadrant and in third angle projection system the object placed in the third quadrant. Engineering drawing is the language of engineers.
