So far the projections of solids are drawn with the condition that a corner (or) an edge (or) a point of the solid is resting (or) touching on any one of the reference planes.

Note that after getting front view and top view in simple position, directly the final front view is obtained without the final top view, which is same as that obtained by change of position method.

If a solid is placed in first Quadrant such that its axis is perpendicular to one of the reference planes (HP, VP (or) PP) then the solid is said to be in simple position.

The position of a solid by refering its axis with respect to the reference planes can be given in any one of the following ways to draw the projections.

It is desired to name the corners and axis systematically so that the projections can be read and understood easily.

The method of drawing orthographic views of solids is similar to that of plane figures, but the third dimension ie., thickness or height of the object is also drawn.
