Have you ever considered using non-Adobe pdf readers? I gave up on Adobe readers when they grew beyond 100MB & incorporated all kinds of security holes & builtin spyware. SumatraPDF.exe is only 5.15MB. Ghostscript.exe is 13.5MB; a little slower, but more flexible. I've heard that some people use Foxit, which is about the same size as Sumatra. Why don't you output "SVG" (Scalable Vector Graphics) format? I believe that SVG now has native support in almost all browsers, including HTML5. http://www.w3schools.com/svg/svg_inhtml.asp For 3D stuff, "STL" format is very popular, but I don't know if there are any STL plugins for browsers yet.
