Architectural Design with SketchUp
TIP
Whenever you define colors using RGB values, keep in mind that the maximum value for
each of them is 255. Here are some sample colors:
[0,0,0] # black
[255,0,0] # red
[255,255,0] # yellow
[125,125,125] # a medium gray

Creating a Small City
Let’s try something similar now: Create boxes with a random height—and let’s call it a city.
As you can see in the following code, we are just producing a 2D grid of boxes. This time,
however, we are using feet as the dimension. And instead of giving all of the boxes the same
height, we are now using Ruby’s rand method to randomize their height (between 100 and
200 feet as you can see in Figure 6.11).
# Creates a small random city
ent = Sketchup.active_model.entities
n = 10 # number of buildings
s = 100.feet # spacing
w = 60.feet # base width
(0..n-1).each { |i|
(0..n-1).each { |j|
# add a face first
