How can one save a 2D part--that is, as connected paths--in Illustrator so that it can be "read" by AutoCAD?

Go to File > Export...

Set "Save as type:" to AutoCAD Drawing (*.DWG)

  • Yes, but how do I know that my manufacturer will be able to read it in his AutoCAD correctly? This part will be lasered out of metal. I keep sending him files, but he keeps saying that there are no lines in the file. Perhaps you have AutoCAD, and you can check. Commented Dec 13, 2013 at 0:09
  • FYI, "lasere"d apparently isn't a word. I checked the OED--how sad. Perhaps "lased" is more correct, seeing how "lase" is a word. Commented Dec 13, 2013 at 0:09

    I just sent .dxf, .dwg, and .svg. Those are the files he can apparently handle. Is there an AutoCAD friendly stackexchange? Commented Dec 13, 2013 at 0:16

    Your Illustrator file had a bunch of open paths. Take a look at this .ai file, or the .dwg and .dxf files: fileswap.com/dl/rCqa6LLcj , fileswap.com/dl/5COELWjbSC , fileswap.com/dl/kMg9Teg1vl

    I opened the dwg and dxf files provided by @TunaMaxx in AutoCAD 2014. The file itself is fine, however, the fact that the shape is filled is a bit alien to most CAD users. So i would eliminate that.

There is no way to guarantee things will work perfectly, that's why you find the functionality under file > export. One of the real problems of illustrator is that the bezier splines used by illustrator can not do perfect circular arcs, so what you get is just approximate. This may be fine in many cases but for general mechanical engineering this is a big problem.
