AutoCAD 2017 can now import PDF files directly. The PDF import will convert lines circles and other geometry, including layers into the corresponding geometry and layers in AutoCAD. I have to say that I was blown away by how good the import is.
Yesterday, I did some tests on a variety of files, and I can report that any vector* PDF that is inserted using the "default" settings will open up with all of the correct layers in AutoCAD.
Check out the Animated GIF below for a workflow showing the import in action. To give you an idea of speed, the GIF is shown in real time.
*You may be wondering what a vector PDF is. PDF's created from AutoCAD, Inventor, Revit and other "drawing" packages generally export out PDF's that contains vector graphics.
"Each of these points has a definite position on the x and y axes of the work plane and determines the direction of the path; further, each path may be assigned a stroke color, shape, curve, thickness, and fill" see https://en.wikipedia.org/wiki/Vector_graphics
For PDF's that contain non-vector graphics, you can still get this information into AutoCAD, but you will need to use Raster Design, have a look at this video for more info. https://www.cadlinecommunity.co.uk/hc/en-us/articles/203113331-AutoCAD-Raster-Design-2016-Quick-Start-Guide
