Hi!
I’ve created a logo for my PCBs using Inkscape - like the Horizon Docs recommend.
But can’t create polygons that have holes.
Any tips how to fix the letter “e”?
Cheers,
jue
The problem is that polygons don’t support holes. To work around this limitation, remove the hole in inkscape as such:
Thank you for your reply! I tried to adapt to your approach and created little tool, that converts many polygons into one. So I’m able to go inside the polygon and create holes.
The idea seems to work, but Horzion doesn’t render this correctly. See the picture below: on the left side you can see my example decal. On the right side you see the correctly rendered Gerber.
The source of my decal:

Is this a bug? Or am I abusing something here?
FYI - I’ve fallen in a deep rabbit hole and learned a lot about polygons … well and I tried to implement a sweep line algorithm, which splits the polygon into segments. I still have to find a bug, but the idea seems to work 
Currently, it’s pure JavaScript and I plan to come up with a SVG Path to Horizon EDA Decal online converter.
