Development of Truncated Cone
A cone, base diameter 80mm and axis 100mm long, rests on its base. It is cut by a plane inclined at 60° to HP and perpendicular to VP, passing through a point on the axis 40mm from the base. Draw the development of the lateral surface of the truncated cone.

Step-by-Step Construction
- 1
Draw the front and top views of the cone
- 2
Show the cutting plane in front view
- 3
Divide the base circle into equal parts (typically 12)
- 4
Project the cutting points on the generators
- 5
Draw the development by plotting the true lengths of truncated generators
- 6
Join the points to form the development curve
Pro Tips
- •Always verify your measurements with a scale before finalizing the drawing
- •Use construction lines lightly and darken the final solution
- •Label all important points and reference lines clearly
