Unable to create new layout

On 025.8 on an Xubunut 18.04 box. The assistant says
Creating A Layout From Scratch
To start with a fresh, empty layout, choose "New" from the "File" menu.

But there is no "New" in the "File" menu!


  • There is "File > New Layout".
    What was the point of your message?

  • It isn't there on my version. I have no layour loaded - do I need a layout loaded for it to allow me to create a new one?

  • I have found you have to change the "Application:Editing Mode" to Use editing mode by default and restart to get that in the File menu!

  • Yes, there are two modes: a viewer (optimized for viewing) and an editor (necessary for creating layouts).

    Yes, there are two modes :-)

    On Windows you'll get three start menu icons: a default (the one you configured in Application/Editing mode), a viewer and an editor mode.

    On Linux (and Windows) with "klayout" you get default mode. With "klayout -e" you'll always get editing mode. With "klayout -ne" you'll get viewer mode.

    In general, viewer mode is more efficient with big files and in particular with OASIS files.
