Coding a Path via Python

bmebu

Hello!
I'm trying to code a path in Python given around 4 points.
https://www.klayout.de/forum/discussion/2056/drawing-path-or-polygon
I used the discussion above as someone had tried implementing this in Ruby and received a reply with a successful code.
I transferred it into Python, but it seems to not work. Can anyone see something that I can't and could possibly help?

TIA!

layout_view = pya.Application.instance().main_window().current_view()
cell_view = layout_view.active_cellview()
layout = cell_view.layout()
viewed_cell = cell_view.cell()

layer = layout.layer(4, 0)

point1 = pya.DPoint(0.0, 0.0)

point2 = pya.DPoint(15.0, 15.0)

point3 = pya.DPoint(30.0, 30.0)

point4 = pya.DPoint(45.0, 45.0)

viewed_cell.shapes(layer).insert(pya.DPath([point1, point2, point3, point4], 1.0))

Hi bmebu

I've tried the code, and it works fine after a small tweak

viewed_cell = cell_view.cell()
viewed_cell = cell_view.cell    #use "cell" instead of "cell()" which causes error

After this you should have a path in your layout, but you might still not able to see anything.

in that this case you need to right click on layer tool box and select "add another layer enteries" in popup menu

and you'll see layer "4/0" shows up and so as the path you added.

Very good. Thanks for this post!

You can insert this statement to make sure the new layer is shown:

layout_view.add_missing_layers()

Kind regards,
