Looking for some help - I have watched the videos that deal with Boolean, weld and subtraction.
I am stuck - when I try to weld the TWO parts together the pick gets removed. What am I doing wrong?
If you select both objects and select the âWeldâ or âBoolean Unionâ tool, you should get something this.
Is this the result you are looking for? You can also read more about how these features work and under what conditions they are available from the link provided below.

Make sure the pick is actually a single closed loop, not just a collection of lines that make that shape.
How do I confirm that? Check for nodes?
To confirm, when you select the pick do you get the entire pick object on a single mouse click? Is the pick object grouped (group marque shows as a dot-dot-dash pattern)? If so, un-group to see if you can get the entire pick object on a single mouse click.
LightBurn also provides âEditâââSelect open shapesâ and âEditâââSelect open shapes set to fillâ to help you find these objects in your projects.
If you do find the pick is not a single closed loop, select entire pick then choose âEditâââAuto-Join selected shapesâ (Alt-J) to close.
THANK YOU!!! I will try that when I get to my computer!
Okay so I tried it - it was not grouped. It goes from this to this when I try to weld.
When I click select open shapes it just picks up the pick but doesnât do anything else? When I click select open shapes to fill it does nothing - I am not sure what I am going wrong but I want them to weld together to be one piece
Select the pick, and go to Edit > Auto-Join selected shapes.
Whatâs likely happened is you imported the pick from a DXF file, and itâs just a collection of lines that happens to look like a closed shape, but isnât.
For example, this looks like a closed shape, but it isnât:
Itâs three closed lines. When itâs not grouped, I can select each of them individually:
This is how LightBurn âseesâ this shape (notice the gaps where the lines arenât connected):
Thatâs what I mean by a single, closed loop - It has to be one continuous curve, or the weld tool canât merge the areas together.
I tried selecting the pick and choosing auto join shapesâŚbut auto join shapes is shaded out and not an option for me to chooseâŚ
Attach the LightBurn project file here and we can take a look.
Path(s) werenât closed.
I just opened it, selected each object individually and clicked âclose pathâ then selected both and welded them just fine.
Thatâs it!!! Thank you!!!
I think I am losing my mindâŚIt worked and then I backed out to make an alignment change and now close path is shaded out and auto join is not shaded out but wonât work eitherâŚwhat could I be doing wrong!!!
Itâs probably still closed - does the weld work? If you only backed up (used the undo) one step, to just before you welded, it would still be the shape you closed.
No the weld does exactly what it did before and then I closed it out because it wasnât working again
I am crazy - now auto join is workingâŚThank you and really I am not crazy - just still learning
