Hi
I'm now studying Ruby Code and using TIG's
"exportvertices2csv"as a teaching material.
I think TIG is putting all the code in initialize,in order to make the code simple.
Although I know that is a wise way. I'm now practicing to rapping it in instance method.
In order to devide it in to "initialize part" and "outputting csv part"
I've wrote these code.
=begin
(c) TIG 2011
Type
Exportvertices2csv.new
in the Ruby Console.
Exports all Vertices is a Selection to a X,Y,Z 'CSV' file.
Edit sep="," if something other than a separating comma is desired e.g. ';'
Make sep="\t" if a TSV file is desired and change ext="csv" to ext="tsv".
It uses the current Model Units/accuracy with the approximate '~ ' and
unit suffix [if any] removed; e.g. change Model Units to 'meters' 3dp to
get exported csv in meters 1.234 - don't use 'fraction' 1' 2 1/2" formats,
always use a 'decimal' format.
1.0 20110105 First issue.
1.1 20110116 Wrapped in protective class.

require 'sketchup.rb'

file=File.new(ofile,"w")
rescue### trap if open
UI.messagebox("Vertices File;\n\n "+ofile+"\n\nCannot be written - it's probably already open.\nClose it and try making it again...\n\nExiting...")
return nil
end
pts.each{|pt|file.puts(pt)}
file.close
puts (pts.length.to_s)+" vertices written to\n"+ofile
begin
UI.openURL("file;/"+ofile)
rescue

return nil
end#if
verts.flatten!.uniq!

end #def
end#class

but recieve this error message.
Exportvertices2csv.new
Error: #<NoMethodError: undefined method `printcsv' for #Array:0xde0858c>
does someone have any idea?
Sincerely yours
