I traced a word sign and it needed some cleanup via node edit. I had the layer set to fill so I could see the progress. Every now and then it would put a rogue node at the home position. I would only notice when I clicked preview it would say I had an open shape. I had the file saved with the rogue node but when I opened it the node was gone.
Has anyone else noticed this behavior?
Here is an example of what I was doing. Separating these two letters. Using node delete and line delete.
Yes. I have seen this and similar behavior. Sometimes svg files that I saved, which looked fine, somehow get corrupted. I’m not absolutely certain that LightBurn is to blame, but I have a hard time pointing the finger elsewhere.
Here’s an example. Typically, when I export an svg, I look at the the thumbnail in Windoze File Explorer and if it looks okay I consider it a success. But sometimes when I revisit the same svg file I get this sort of thing and the thumbnail is bogus. Very annoying.
There have been a bunch of fixes and cleanup done to node edit for the upcoming 1.3.00 release. There were cases where breaking and re-joining could create shape lists that confused other code. It’s been very stable since these changes.
I traced a jpg file in LightBurn and it looked okay, so I exported the svg to my graphics library on my PC’s hard drive. Browsing through the library today I noticed the preview was wonky so dragged it into LB and got this mess. So I selected the mess at the top and deleted it and ended up with this:
It doesn’t surprise me that Inkscape wouldn’t show it the same way as LightBurn by default. LightBurn will negate all overlapping shapes of the same layer irrespective of grouping and does not expose a compound path concept. In contrast, Inkscape by default will only negate overlapping portions when they have been combined into a compound path.
Try this in Inkscape:

This should result in basically the same look as in LightBurn. There may be some slight differences due to handling of stroke width. You can adjust for that by setting a stroke in Inkscape and adjusting the stroke width.
