Draw
to a scale.
A
- Locate the three basic lines to find the visual field:-
|
|
support
line |
|
|
horizon
line |
|
|
distance
line. |
B
- Draw a perfectly geometric square on the support line, with
the vertical and horizontal lines parallel between them.
C
- Divide the square in the middle and draw at this point a vertical
line that goes from the support line to the distance line. Mark
the vanishing point at the intersection of this line with the
horizon line. Always on the middle of the square and from the
support line, mark the visual distance (17cm to scale) and locate
the view point.
D
- Now find the depth point on the horizon line, placing it far
away from the vanishing point, in the same proportion that the
view point is located far from the distance line. See figure
nº 10.
E
- Draw four converging lines to the vanishing point starting
from the four vertices of the square on the horizon line, which
is the remotest view point.
F
- Draw two diagonal lines from the square vertices to the depth
point. At the intersections of these lines going to the vanishing
point, you will find the cube depths. See figure nº 11.
Now, join points a, b, c, d
– and you will have a cube constructed to scale in millimeters.
