It does not work in Kicad version 7.0.1

[wiserst]

Hi, since Kicad version 7.0.1 (still a test build), Pcbdraw stopped working for me. When I go back to version 7.0.0 it works.

Command Prompt:

• KiCad 7.0 Command Prompt

You may now invoke python or pip targeting kicad's install

Could you share the board (or at least outline without components) where it fails? I struggle to reproduce the behavior.

[wiserst]

Yes, here is the whole project. Thank you.

Here is a generated png from PcbDraw and Kicad 7.0.0

Hi @wiserst !

The problem is with the rectangle used for the edge cuts.
As a workaround: replace it by 4 lines.

BTW: Using fonts for your PCB makes it hard to share with others. KiCad introduced fonts support, but lacks a mechanism to embed them.

Hi @yaqwsx !

The problem is that KiCad 7.0.1 is generating polygon paths, in this case a rectangle:

M 78.7300,28.0000 138.7300,28.0000 138.7300,96.0000 78.7300,96.0000 Z

But it can be anything:

M 108.7300,56.0000 138.7300,96.0000 78.7300,96.0000 78.7300,28.0000 138.7300,28.0000 Z

The following patch solves the problem:

Is quite lame because it decompose the polygon ... and then the code recreates it. But has a small impact in the code.

I overlooked a variable name collision.

hi, has there been an update for this?
