You may want to add another link to your list Ken if you don't already
have this one. Or at least take a look here:

 http://www.3dlinks.com/tools_converters.cfm

I've used gif2dxf before but the results were strange to me. Never
figured what use it was. However there is another program mentioned
there that does the 2D to 3D conversion.
