𝑷𝒓𝒐𝒃𝒍𝒆𝒎 𝑺𝒕𝒆𝒑𝒔:

1. Drawing top view and front view of the cone
2. Locating the section plane and drawing the section line
3. Drawing the sectional front view
4. Drawing the true shape of the sectioned surface

This important problem is visualized using solid models of a cone, making it easier to understand each step.
