How can you import a file from Adobe Illustrator to AutoCAD?
From Adobe illustrator you can
1) Export as .dxf (which is readable by autocad)
2) Select Location to save the file.
3) Run AutoCAD
4) Open the .dxf file saved earlier
some problems may arise when importing such file, you just have to choose an appropriate resolution.
I have been following several methods, by far the most convenient and efficient way uptill now is
Scan2CAD : http://www.scan2cad.com
It’s an application that you throw at it any picture and it converts it automatically into a CAD file,
I have been using it to convert files from Adobe illustrator ‘s PNG or SVG to .dxf files readable by AutoCAD
