No shape button on the menu bar


I changed my pc to macOS, and I am adjusting Klayout in macOS.
However, when I used Windows, I got shape buttons ex)box, polygon, instance e.t.c.
but, now, I have only select, move, and ruler.
I think since I have no instance, I cannot even drag and drop from Libraries which is left middle of the picture.
Before, i could drag and drop to create an instance.

How can I solve this problem?

Thank you very much in advance. :)


  • Hi,

    you are running KLayout in viewer mode.

    In order to get these functions, you have to use editor mode.

    On Linux that's "klayout -e ...".

    On Windows, there is a start menu entry saying "KLayout (Editor)"

    On MacOS I think there is something similar (I'm not a Mac user myself).

    Or you configure it to use editor mode by default in the Setup Page (File/Setup):


  • Thanks a lot! :) it works very well.
