The drawing shows the development of the lateral surface of a solid using standard geometric methods. Development is the process of unfolding a 3D solid into a 2D plane to represent the true size and shape of its surfaces.

In this drawing:
The solid is assumed to be a right solid
The lateral surface is unfolded onto a plane, while the base and top are usually not included unless required.
The method used depends on the solid:
Parallel Line Method is used for prisms and cylinders.
Radial Line Method is used for pyramids and cones.
If the solid is truncated, the development accurately shows the true shape of the cut surface.
This development is useful in sheet metal work, packaging design, and manufacturing where flat patterns are needed for fabrication#cad #engineering #drwing
