ENV["LD_LIBRARY_PATH"] is for standalone Ruby. I'm surprised if it works at all in embedded Ruby. Same for Open3. I've heard of nothing but problems with it under SketchUp embedded Ruby. Suggest you try to wrap Emp using the Ruby Fiddle library ... http://ruby-doc.org/stdlib-2.2.4/libdoc/fiddle/rdoc/Fiddle/Importer.html P.S. - Your code is hard to read on GitHub because your indents are being replaced with 8 spaced TABs. Ruby looks best with 2 space indents. Most code editors can replace TAB with space characters as you type, and you will not get these giants indents when you post code.

It worked wonderfully! I was using the load_from_url method with a file:// prefix before, and it also worked... but this makes more sense. Thanks!

Thanks, Dan! Your answer does give A LOT of food for thought. I will try someof these and let you know. Regards
