margin and title box then:
Measure intervals of 24mm (1") along the base margin as shown and
join to RVP.
Where they cross the vertical line from CVP draw horizontal lines as
Add lines to CVP from marked intervals
Extend and complete.
Shade alternate tiles.
Add two more rows to the outside.
Clean up with eraser if necessary.
What does RVP stand for?
What is the horizon?
How is it we can make a drawing with depth on a flat surface?
EXPLAIN : The 'flat' surface is like
a window or a sheet of glass. It is called a 'picture plane' (PP). The 'observer',
the person looking is standing a distance behind the PP and the
floor is a particular distance in front of the PP.
this point we need to interrupt our drawing to learn to draw circles. Since we have no tools to trace or guide us we will need to learn to draw these - freehand.
We need to know this to complete our current project. So start a new sheet and
