I would like to 3D print some Mathematica-generated polyhedra, but I can't figure out how to download the files generated from the 'Export' command. For example:

Export["myTestModel.stl", PolyhedronData["Dodecahedron"]

gives as output

myTestModel.stl

Which looks like a success! However... the result file is not visible in my "Cloud Files" directory. Where does Mathematica Online store exported files?

  • $\begingroup$ Use CloudExport. Export doesn't work. I too found this out the hard way, and for the life of me I cannot understand this "design" decision. $\endgroup$ – user6014 Jan 19 at 3:29
  • $\begingroup$ The Directory[] command returns the current default directory for files, including Import[] and Export[] and FileNames[] returns a list of filenames in the default directory. $\endgroup$ – Somos Jan 19 at 3:32
  • $\begingroup$ Apparently Directory[] shows the files in the actual Linux server the Wolfram Cloud is built on top of, which somehow slightly differs from the actual cloud file directory (I noticed there wasn't a 1:1 match with files). It's awfully confusing. I'm also not sure how secure things are there, and how much access someone has on the server itself if they're particularly creative. $\endgroup$ – user6014 Jan 19 at 3:34

    $\begingroup$ The file commands are designed for working on a personal computer and have been in Mathematica for a long time. The cloud commands are relatively new and specifically designed to work with objects in the "cloud". No direct connection between the two functionalities. $\endgroup$ – Somos Jan 19 at 3:37

After you run the Export command, on the next line type:

ExpandFileName["myTestModel.stl"]

The output will show you the full path filename.
