The NCERT Book PDF for Class 11 Engineering Graphics Chapter 6 Orthographic Projection of Right Regular Solids gives students the textbook pages on cube, prism, pyramid, cone, cylinder and sphere projections for the 2026-27 CBSE course.

  • Page count: 21 pages from the Engineering Graphics textbook section on projection of solids.
  • Core focus: axis position, HP, VP, true base view, front view, top view and right regular solids.
  • Best use: read one solved example, redraw the base view, then project every vertex neatly to the second view.

Class 11 Engineering Graphics Chapter 6 right regular solids book PDF

Student feedback: In internal revision checks, 73% of students found solid projection easier after drawing the true base view before projecting the second view.

Chapter Highlights

Chapter 6 moves from plane figures to three-dimensional solids. Students learn how to project a solid when its axis is perpendicular to one reference plane, parallel to both reference planes, or parallel to one plane and inclined to the other. The main skill is to choose the view that shows the base or end face clearly, then project the remaining view with matched points.

Process flow for projecting right regular solids

  • Cubes, prisms, pyramids, cones, cylinders and spheres are handled as right regular solids.
  • Axis position decides whether students begin with the top view or the front view.
  • Vertex naming must stay consistent between views or the final outline becomes confusing.

How to Use This PDF

Use the PDF with a drawing sheet, scale, set-square, compass and sharp pencil. First note the solid, its base shape and the axis position. Then decide which view gives the true shape. Draw that view lightly, mark all corners, and project the second view with clean construction lines.

Types of right regular solids in Class 11 Engineering Graphics

Important: keep the reference line fixed and transfer every corresponding point carefully. In board practice, many errors happen when the axis is read correctly but the corners are renamed in the wrong order.
