Frequently we find maps in pdf, which have been generated from a mapping program, therefore vectorial and we want to import them into ArcMap or AutoCAD. It is curious that being the pdf a well-known format, to which all export and that now even has georeferencing properties none of the popular mapping programs has developed the function of importing even those that he himself generated.
Here are two alternatives.
1. Through a graphic design program
This can work either Adobe Illustrator or Freehand.
The output is to import them from the design program, then export them to dxf that can open any CAD / GIS program, of course you have to understand that the dxf alone has no georeference
2. Through AideCAD
This is A program which converts vectors from pdf to dxf format
Unfortunately both are payment programs although there are trial versions that can get you out of a hurry.
3. Through another solution
I remember seeing another more practical solution, but now I do not remember it; we leave the space for someone to tell us if there is another alternative ... then we finish the post.
