The orthographic projections (projections of point P on HP, VP and AIP) of point P can be obtained be the following steps.
- Draw the XY line and mark p and p', the top and front views of the point P.
- Since AIP is inclined at q to HP, draw the X1Y1 line inclined at q to the XY line at any convenient distance from p’.
- Since point P is at a distance n infront of VP, the auxiliary top view p1 will also be at a distance n from the X1Y1 line.
- Therefore, mark P1 by measuring o1p1=op = n on the projector drawn from p‘ perpendicular to the X1Y1 line.

Draw the top and front views. |
Draw the top and front views |
Draw X1Y1 line inclined at f (the inclination of AVP with VP) to the XY line. |
Draw X1Y1 line inclined at q (the inclination of AIP with HP) to XY line. |
Draw the projectors through the top views of the points perpendicular to the X1Y1 line. |
Draw the projectors through the front views of the points perpendicular to the X1Y1 line. |
The auxiliary front view of a point is obtained by stepping off a distance from the X1Y1 line equal to the distance of the front view of the given point from the XY line. |
The auxiliary top view of a point is obtained by stepping off a distance from X1Y1 line equal to the distance of the top view of the given point from the XY line |
