Orthographic Projection in Engineering Drawing | 1st & 3rd Angle | Why Not 2nd & 4th?
orthographic projection,
how to draw orthographic projection,
how to convert 3d to 2d views,
1st angle vs 3rd angle projection
2nd angle and 4th angle projection
Orthographic Projection is one of the most important concepts in Engineering Drawing, CAD, and Technical Drafting. In this video, I explain:
✔ What is Orthographic Projection?
✔ Why do we use Orthographic Projection in engineering?
✔ What is the difference between First Angle and Third Angle Projection?
✔ Why Second and Fourth Angle Projection are not used in real-world technical drawings.
✔ How to convert a 3D object into 2D orthographic views step by step.
If you are a student of Engineering Graphics, Diploma, ITI, Polytechnic, Mechanical Engineering, Civil Engineering or preparing for exams, this video will help you understand the concept clearly and correctly.
Watch till the end to fully master the topic with examples and clear explanation.
