HI all,

I am very much a noob to Inkscape though I have been trying for the past couple of weeks to work out how to do this. I will also apologise in advance that my use of language is probably not that technically correct, just trying to explain things as best I can.

Situation;
I have a laser engraver which can burn wood. That's my end goal :)

And I've achieved this to some degree but not exactly what I wanted.

The line drawing I have is very simple

*Line Drawing.png

The issue I am experiencing is that when I "Object to path", "Stroke to Path" or "Trace bitmap" (as my step along the way to generating the GCode)

The result is the path runs both sides of the line:

Path.png
*Path.png
(78.48 kB . 995x660)

I've tried to alter the settings on each of the "Object to path", "Stroke to Path" and "Trace bitmap" to try to get a single pass but am not having any luck.

I have been trying to go in and delete the unnecessary paths but the process is extremely laborious. It's not that I don't mind hard work just hoping that there is a simpler solution.

I've also included a Zoom in on the original image. I understand that the reason for the two paths is that the line is more than one pixel wide.Line Drawing zoom.png

Any help would be greatly appreciated.

Welcome aboard!

Just recently this topic was posted.

I'd say you may find an automated way for centerline tracing but that probably won't work so well on lines intersecting.

Hi Lazur,

Thank you so much. Greatly appreciate it. The other thread has exactly what I need (well on the surface it looks perfect, will let you know in about an hour once I've traced and burnt)

Can also see why I couldn't find it, I need to get more use to he vocabulary,

Any way,

Thank you again so much for the support and assistance.

Jon
