10+ Junior Design Engineer Interview Questions and Answers for Freshers

Angle projection methods are used in engineering to represent 3D objects on a 2D plane. There are two main types of projection methods: orthographic and perspective.

• Orthographic projection method shows the object as it looks from the front, top, and side views without any perspective distortion.

• Perspective projection method creates a more realistic representation of the object by accounting for perspective distortion.

• Examples of orthographic projection include first angle pro...read more
