Save and open a .kerf file

Copy page ▾

A .kerf file holds the complete project: parts, materials, finishes, parameters and the imported models it uses. Use it as a backup, or to move a project to another browser or another person.

Save a .kerf file with the assistant conversation#

Do these steps for a draft. For a saved project, see Download a saved project as a .kerf file.

  1. Select File ▸ Save…, or press Ctrl+S (⌘S on a Mac).
  2. Select Also download a .kerf file.
  3. Select Include the assistant conversation in the file.
  4. Click Save.

The file holds the conversation and the token usage. It never holds credentials.

Download a saved project as a .kerf file#

  1. Select File ▸ Download .kerf…. The Download a .kerf file dialog opens, and Also download a .kerf file is selected.
  2. If you want the conversation in the file, select Include the assistant conversation in the file.
  3. Click Download. The button shows Writing .kerf… until the file is ready.

KerfCraft saves the project and downloads the file. It does not make a copy of the project. If you change the Name, KerfCraft renames the project. The menu shows Download .kerf… only for a saved project. For a draft, use File ▸ Save….

Save a .kerf file without the conversation#

Use one of these:

  • In File ▸ Save… or File ▸ Download .kerf…, select Also download a .kerf file and clear Include the assistant conversation in the file.
  • In File ▸ All projects…, click More actions on the row of a project, then select Export .kerf….
  • In File ▸ Import / Export…, on the Export tab, select KerfCraft package (.kerf) and click Export….

The Export tab shows what the file keeps and a list of checks on the project before you export it.

If your browser can show a save dialog, it asks where to save the file. If not, the file goes to your downloads folder. The status bar shows the name of the file when it is saved.

Open a .kerf file#

  1. Select File ▸ Open file….
  2. Select the .kerf file.

The file opens as a saved project, and the status bar shows Opened and the file name. If the file holds an assistant conversation, the conversation opens with it.

If the same project is already in your projects, the file opens as a separate copy. Your saved project does not change.

To add the contents of a .kerf file to the open project instead, use File ▸ Insert from file….
