Is there not a very problematic and a cheap way to convert my AutoCAD 3D technical drawings to browser acceptable format, probably, flash? I'd like to put 3D drawing to a site in a way visitors could rotate them with mouse drag-and-drops clicks, well, like Google 3D panoramic street view.
Export/save in Autocad to the X3d format, upload that to your site, and use a VRML plugin for any of those listed players to view the file. Which means providing a link on the page for others to download the plugin so they can do the same thing.
Here's a solution which uses a Java applet. It's universal if you consider Java Runtime is on most computers. No plug-in installation required, just needs a browser. Works on Mac and Windows. Learn more here: http://altadyn.com/developers-api/
