Cococart Ventures Interview Questions and Answers

First angle method and third angle method are two different approaches used in engineering drawings to represent the 3D views of an object on a 2D plane.

• First angle method is commonly used in Europe and Asia, where the top view is placed below the front view and the right side view is placed to the left of the front view.

• Third angle method is commonly used in North America, where the top view is placed above the front view and the right side view is placed to the right of the...read more
