Answer Posted / kiran
in 1st angle projection the front view will be in the top of
the xy plane and the top view will be in the bottom of the
xy plane
.In 3rd angle projection the top view will be in the top of
the xy plane and front view will be in bottom of the xy
plane. dis will give a clear view.i hope u know dis... but
in 2 angle projection both the views(front and top) will be
in the top of the xy plane and in 4th angle projection both
the views (front and top) will be in the bottom of the xy
plane... since both the views will be in one side of the xy
plane, its not possible to draw... both views will merge...
to get more clear view, refer any basic engineering drawing
book.......
Second and Fourth Angle Projections are not used to avoid
confusion in having multiplicity of the projection usage,
and also to have a standard practice in simplifying the
drawing methods.
