The NCERT Book PDF for Class 11 Engineering Graphics Chapter 7 Section of Solids gives students the textbook pages on section planes, sectional views, hatching, points of intersection and true shape of sections for the 2026-27 CBSE course.
- Page count: 56 pages from the Engineering Graphics textbook section on sectioning simple solids.
- Core focus: prisms, pyramids, cylinders, cones, spheres, cutting planes, section lines and auxiliary true shape construction.
- Best use: study one construction at a time, then redraw the front view and top view with a light pencil before hatching the section.
Student feedback: In internal revision checks, students made fewer sectioning mistakes after marking the cutting plane arrows before drawing the sectional view.
Chapter Highlights
Chapter 7 explains how an imaginary cutting plane is used to reveal the internal details of a solid. The sectional view replaces a normal outside view when hidden details would otherwise make the drawing crowded. Students learn how to identify the section plane, project points of intersection and show the cut surface using neat hatching.
- The cutting plane is shown by a chain thin line with labelled ends and arrows.
- The exposed cut surface is hatched with thin parallel section lines.
- Curved solids need careful POI transfer so the sectional boundary is smooth.
How to Use This PDF
Use the PDF with a drawing sheet, mini drafter or set-square, compass, scale and sharp pencil. Read the problem statement first, then decide whether the cutting plane is parallel to HP, parallel to VP, inclined to HP or inclined to VP. This decision tells you where to mark the section plane and which view becomes sectional.
Important: do not hatch the entire object. Only the surface actually exposed by the cutting plane is hatched, and the hatching should not run through dimensions or labels.
