Hi All,

After I updated the SiEPIC packages, now everytime I use "path to waeguide", it threw an error "Layout object has no attribute technology",

Details is as below:

'Layout' object has no attribute 'technology' C:\Users\Rui Cheng\KLayout\salt\siepic_tools\python\SiEPIC\extend.py:688 C:\Users\Rui Cheng\KLayout\salt\siepic_tools\python\SiEPIC\scripts.py:515 C:/Users/Rui Cheng/KLayout/salt/siepic_tools/pymacros/Keybindings/Waveguides/Path to Waveguide - Hotkey.lym:5

Could anyone help me fix this? Thanking you! Rui

Hi Lukas，

Although not confirmed yet, I think the issue is because I was using KLayout 0.26.8, while "Technology" method is not available untill Klayout 0.27

According to Description of "Technology" method in Class Layout on （https://www.klayout.de/doc/code/class_Layout.html#method127)

"This method has been introduced in version 0.27. Before that, the technology has been kept in the 'technology' meta data element."
