Ortographics views of the point
Monge projection and oblique view of the cube and the point P. Change the top view P1 or/and front view P2 of the point.
Rule:
Straight line P1P2 joining the horizontal and vertical projections of the same point is perpendicular to the base line x12 . Part P2P0 above the base line gives the elevation of the point P above the horizontal plane and residual part P1P0 below the base line is distance of it from the vertical plane .
Let base line is intersection of projection planes. If point P lies in the projection horizontal plane , than
Construction
The vertical planes and are given by projections. Construct adjacent views of arbitrary points and .
