Ruby - find a model's maximum height

[Thaje]

Hello, I have searched google tirelessly for the past two hours and have not found anything remotely like I am trying to do, so I appeal to the great minds of sketchucation.

I started ruby programming tonight so know very little. I am trying to create a ruby script which finds and saves the maximum height, length, and width of a complicated model (eg. The statue of liberty, or something) to a text file. Sounds simple, and I think it is, but I have no idea were to start.

If someone could point me in the right direction I would be very grateful.

    file = File.join(filepath, filename).tr("\\","/")
    f = File.new(file, "w")
    f.puts(x)
    f.puts(y)
    f.puts(z)
    f.close
    ### Tip; to make a 'spreadsheet' file change suffix to ".csv" or ".tsv"
    ### and then 'puts' one line only, thus; f.puts(x+","+y+","+z)

Thanks man, this looks exactly like what I'm after. Now I just have to work through and understand it...
