Problem? Tracing Image and placing inside another object does not reverse image

Experiencing a really odd issue here. If I draw a box on the screen with a FILL layer, on preview its a solid box. If draw another shape and put inside the box, it will reverse for that shape. 100% correct. Note the white star.

But if you TRACE an image to get a path, and put that traced path inside the box, it does not reverse! Note the TRACED in that same image.

All the same layer settings (standard fill)!

If I click on the TRACED, and move it outside the black box, its fine and fills in like it should. All paths are closed!

It seems that something is wrong in the grouping perhaps? If I ungroup the traced image, then it works properly. But it does not matter if its only one object, or several in the trace.

Seems this might be a bug?
VIDEO: Video showing the issue

I think it is an issue of layer order. Try putting the text on a different layer and repeating the exercise.

Also try drawing the box and the text in the reverse order and repeat your exercise.

Nope. Again, that text is not really text it is just a trace of an image. It can be anything traced from an image and it does not work. It is on the same layer and set for fill like the outer object. Even if a different layer, it does not work.

However I can make a square (filled) and then make another square (filled) inside that one and it works as it should.

If I trace any image, say a simple object like a star, and put that inside the square it does not reverse like other objects. I’ve tried this on both my computers and both are doing the same exact thing. It seems related to the trace function.

I also found that if I take that traced object and do an OUTLINE, the outline also has that strange issue as well. Both the outline AND the original traced object do not reverse!


This is what I get when I trace your vector graphic. (It’s not an image)

What do you think is wrong with the offset function? Can you explain what you expect?

Maybe this video will help you understand the issue.
Problem with nesting a traced object

Double click your Fill layer settings. Do you have it set to “Fill all shapes at once”? If you don’t, and it’s set to “Fill groups together”, then the grouping will affect which shapes get filled at the same time.

Everything that’s not in a group is treated as a single group for the purpose of filling when in this mode, so if ungrouping everything fixed it, that’s most likely why.

Hello Oz!

Thank you for the suggestion. However that made no difference.

It seems when you trace an item it is given a different property than a regular drawn path? And if you make an offset shape from that traced object, the issue carries over to that item as well.

Here is another video showing in more detail, and with me changing the group/layering as you suggested.

Note that when I ungroup the traced triangle (which is not a complex object, but a simple single closed single path), it then behaves normally and as expected.

Thanks!

Can you attach the project file you’re working with here?

In your optimization settings, you have “Order by Layer”, then “Order by Group”, and finally “Order by Priority”.

Each of those items is handled in turn, so it works like this:

  • Collect all shapes into a list
  • Since “Order by Layer” is enabled, break everything into sub-lists by layer
  • Since “Order by Group” is enabled, for everything we have so far, break those lists into sub-lists by group
  • Since “Order by Priority” is enabled, take all the lists we have so far and break them up by shape priority (all your shapes have priority zero, so this does nothing)

If you make your optimizations look like this, things will behave the way you think they should:

Thanks OZ!

That was very confusing because I was working all in the same layer and drawing a square, then making a trace right after so I would not think those other settings would have anything to do with it.

At least now I understand better. Have a great weekend and thank you for the awesome support once again!

Here is what I get when I drop your file into LightBurn.
Isn’t this what you are looking for.

Oz,
I’m guessing my settings are as you showed. I’ll be darned if I can find Cut Optimization Settings even though I have seen it before. Where is it in LightBurn?

Thank you. Turns out they were all on. Not Now. :slightly_smiling_face:

You can click the “Reset to defaults” button on the bottom to get the set of optimizations that we recommend for general use. For things like ornaments, where you want them to complete one at a time, Order by Group first, then Order by Layer.
