It is generally used for polyhedron, single curved surfaces, and warped surfaces
Ruled Surface
Plane
Radial Line Method
It is one that may be generated by sweeping a straight line, called the Generatrix, along a path, which ma be straight or curved
Plane
Double-Curved Surface
Ruled Surface
Single-Curved Surface
It is generated by a curved line and has no straight-line elements. Common examples are the sphere, torus, ellipsoid, and hyperboloid
Single-Curved Surface
Plane
Double-Curved Surface
Solids
It is a ruled surface that is generated by a line, one point of which moves along a straight path while the generatrix remains parallel to its original position
Plane
Single-Curved Surface
Radial Line Method
Solids
It is a developable ruled surface; that is, it can be unrolled to coincide with a plane. Example are the cylinder and the cone
Double-Curved Surface
Single-Curved Surface
Plane
Ruled Surface
It is a geometric solid that one whose top has been cut off at any angle and at any distance above its base
Truncated
Frustums
Trunkated
Frostoms
It is cones and pyramids that are truncated parallel to their bases
Frustums
Truncaated
Frustoms
Trunckated
It is employed for pyramids and single curve surfaces like cones in which the apex is taken as center and the edge as radius for its development
Solids
Parallel Line Method
Radial Line Method
Triangulation Method
It is used for developing prisms and single curve surfaces like cylinders/prisms in which all the edges of the lateral surface are parallel to each other
Radial Line Method
Triangulation Method
Solid
Parallel Line Mehod
It is very useful in sheet metal work, construction of storage vessels, boilers, and chimneys
