Architectural Design with SketchUp
Figure 6.15 shows the result of importing a large file consisting of point coordinates
using the method described here. The raw data in this case came from a LIDAR flyover of a
historic church.

Working with Text Files
As the preceding example shows, it is quite easy to work with text files. The common
approach to reading from a file is this:
filename = ‘data.txt’
f = File.open(filename)
f.each { |line|
# Do something with the line here
}
f.close
Alternatively, you could replace the middle three lines of this code with content =
f.readlines, which reads the entire file as an array into the content variable. You would
then use content.each to iterate through the lines.
To write to a file, use this syntax:
filename = ‘data.txt’
f = File.new(filename,’w’)
