How to draw 3-D objects on 2-D isometric dot paper.

Three different views of 3-D shapes: top view, view and front view.

Polyhedron : Solid objects having flat surfaces.

Prism : The polyhedra have top and base as polygon and other faces are rectangular (parallelogram).

Pyramids : Polyhedron which have a polygon as base and a vertex, rest of the faces are .

3-D objects could be make by using 2-D .

Euler's formula for polyhedra : E + 2 = + V.
