Is it possible to save a SW drawing which has shaded view as a dxf or dwg and still maintain the shading?

I am trying to open the view into Adobe Illustrator. Best option that I have found without getting pixelated image when I zoom in, is to save as dxf or dwg. Problem is result lacks the shading/color as was in the SW drawing view. When open in AI, I can only see the lines, but the color/shading are missing.

Any suggestions? Can DWGeditor edit/add the color?

Thanks for suggestions and ideas.

Rgds,
