In this session, we’re solving one of the most interesting and exam-relevant 3-in-1 problems from Engineering Graphics — combining concepts from:
1️⃣ Projection of Solids
2️⃣ Section of Solids
3️⃣ Development of Surfaces

The given solid is a Right Regular Triangular Pyramid (Base 30 mm side, Axis 60 mm).
We will:

Draw projections (front & top views) in two steps,

Introduce a vertical cutting plane parallel to VP,

Obtain the sectional front view, and

Finally, construct the development of the remaining solid surface.

🎯 Concepts Covered in this Video:
✅ Projection of Solids (Triangular Pyramid resting on HP)
✅ Section of Solids (Cutting Plane Parallel to VP)
✅ Development of Lateral Surfaces (True Length Method)
✅ True Length of Slant Edges
✅ Step-by-Step Construction of Sectional Front View
✅ Full Development of the Retained Portion

📘 Ideal For:

First-Year B.Tech / Diploma Students

Universities: SPPU, GTU, RTMNU, AKTU, JNTU and others

Students preparing for Engineering Graphics / Engineering Drawing exams

💡 Why Watch This Video?
Because this single question combines three chapters and tests your understanding of projection logic, section visualization, and development geometry — all in one go!
Perfect for university exams, vivas, and competitive tests.
