Path or Polygon？

[Zahi28]

Hello，
I find this gdsHelpers very easy to use for describing 2D-masks. But, can I create a path with it? Because I need to use FBMS to get a long waveguide that's not broken and across several writing fields. For example the length of waveguide is 800um and the writing field range is 100um * 100um.

Hey, nice to hear that you like gdshelpers!
I've recently added support for paths in 700cf9a, but it was not yet included in the pypi-release. I've just released v1.2.0, where it's also included.
After updating you can use e.g. cell.add_to_layer(3, LineString(((0, 0), (100, 100)))) to add a Path to your design.
Hope that helps! Please let me know if it works for you.

With your help, I successfully added a path! But how can I set the width of the path, as shown in the figure below?
