How to show autocad (dwf, dwg) files in browser?

HI, I have downloaded Volo View Express from www.autodesk.com (plugin to web-browser) and can see the sample autocad-file that is presented on their site. Code ment to display the file drawing1.dwg on my page (none working): 1) <img src="drawing1.dwg"> Displays no image. 2) <OBJECT data="drawing1.dwg" type="image/vnd.dwg"> A nice drawing. </OBJECT> The only thing I can see is a blue rectangle whith the following error message inside it: "Drawing File Format Unrecogr" 3) <object> <param name="Filename" value="drawing1.dwg"> <embed name=thanks src="drawing1.dwg" pluginspage="http://www.autodesk.com/whip"> </object> The only thing I can see is a blue rectangle whith the following error message inside it: "Drawing File Format Unrecogr" I'm running Apache 1.3.26. This is what I have written into httpd.conf: AddType model/vnd.dwf .dwf #drawing/x-dwf .dwf AddType image/vnd.dxf .dxf AddType image/vnd.dwg .dwg This is what I have written into mime.types and mime.types.default: image/vnd.dwg image/vnd.dxf Appreciate any help.
