I've downloaded the latest Cura AppImage (slicing software for 3D printing) and I'm running the optional AppImageD. This AppImageD deamon should automatically "install" Cura. It for example adds it to the Applications menu.

Cura however isn't added to the "Open with" dialogs, even when viewing all applications. Even though it's .desktop file contains the following MimeTypes:

  • application/sla
  • application/vnd.ms-3mfdocument
  • application/prs.wavefront-obj
  • image/bmp
  • image/gif
  • image/jpeg
  • image/png

I'm not sure what is causing this, whether it's Cura's AppImage, AppImageD or elementary OS.

The Cura 2.7 version that's installed from the ppa is added to the "View All Applications" list. It's .desktop file:

David Hewitt on Slack pointed me towards an issue, the Exec of the AppImage desktop file doesn't have the %F argument, meaning it can't open files. After adding it, see below, it shows up in the View All Applications list.

Exec=/home/peteruithoven/Downloads/Cura-3.2.0-BETA.AppImage %F

Update: After more tips from David, this led to the following AppImageD issue: https://github.com/AppImage/AppImageKit/issues/642
