Assignment due:
Color handout completed and
Playhouse model built
Session 4 - Shadows
During class time today work on 3 different color
schemes for your project - make a print and do
different color schemes on the print. The schemes
must be able to be categorized as one of the ones
discussed in class.

There should be a dominant hue, value and
chroma for the scheme to work best. To liven it
up have subordinate elements create tension.
This contrasting element can be hue (greenred), value (light-dark) or chroma (rich yellow,dull yellow).
Use a board underneath so the color doesn’t
bleed through.
Lay down the colors in parallel lines in the
direction of the material you are representing.
When complete, we will select the best one.
This scheme will be the one you’ll use on your
final project.

Color on the floor plan usually works best with
monochromatic/neutral schemes.
Exterior elevations usually will be rendered more
realistically. Try to mimic actual colors.
We will use this scheme in your final presentation.
Write down the pen numbers so you can do the
colors on the final scheme.

Today we’re going to look at shades & shadows especially in elevation views. As always there are
standards. This is not for actual shadows but
suggested shadows. It is a standard.
During class today you need to show me the
model and we will have to digitally photograph it.
The photo will be included on your presentation.

Shadow Standards
If we want true shadow lines we
would need to know the inclination
of the sun during summer, winter
and spring/fall equinoxes. We
would need to know the
orientation of the building as well.
Some CAD programs can
generate this. Some cities require
this in every project.
Imagine a point of light traveling through a cube of space. The light
is going from corner to corner. If we were looking at it in elevation
view, it would look like a 45 degree line going from top right to
bottom left. If looking in plan view, it would look like a 45 degree
line going from bottom right to top left.

Most plan book would have this type of casting. Notice that
they are just elevation drawings with shadows put on. We
could never see the building like this. There would be
perspective in real life! But it is a quick way to show depth.
This is what we’ll be doing with our projects.

To cast shadows, imagine a point of light traveling across the
object (45 degree in plan and elevation). If the point of light is
stopped, a shadow will be created. We then use our geometric
principals to construct the shadow. The points of light that are
important are those on the edge.

The plan & elevation can create the correct shadow.
Imagine casting the shadow of the first triangle, then
the second and connecting the points.
Although this is a “suggestive” technique, you
can test it out on a model and a lamp. Put the
light 45 degrees from the model and look at it.
The correct standard shadows will form. You
can also see what real sunlight will do by
orienting a model of the project near the site
location on a sunny day. To get the full effect
you must go out during the equinoxes in a 6-9
month cycle (winter, spring or fall, summer).

The shadows of
complex objects are
the sum of the
shadows of simple
shapes. When
creating shadows of
complex objects –
break them down to
simple shapes.

The shape of a shadow is
dependant on the surface it falls.

West Publishing Company 1994, p.125-126
The length of
a shadow is
the height of
the shape.
Cast the
shadow line
45°in plan
and elevation.

Sometimes shadows don’t always hit a surface. For
example, the shadow that falls off the edge of the
building - where did it go?

An example of how shadow falls on an angled plane.
You use the same technique. Work in plan as well as
side elevation to get the full image.
Look at Shadow
Worksheet of cabin.
We will be casting a
shadow on our
project elevation
views to make it
look real. This
handout will give
you some basics.
Let’s add shadow to
the south elevation.
To set up place plan
above elevation.

Step 1
Cast 45°lines on
plan and elevation.
Step 2
Bring lines down
from plan to
elevation.
Step 3
Connect lines at
intersections.
Step 4
Clean up
connections.

Step 5
Look at details.
Step 7
Shade without
covering up
lines below.
Compare hand-drawn shadows with model
Step 6
Add small shadow lines.
What a difference
shadows make!
Now it is your turn to do the other three elevations. The
East elevation is tricky because you need to use the
same technique as discussed earlier.

When done with the exercise - we will
check with model of cabin. NO looking at
model till all done!
Use CAD and create a separate shadow layer (red),
use an open hatch (user defined, 45°, 1”) to fill
shadow area. Then begin to cast a shadow using
the same techniques in our handout.
Assignment List
