I’m wanting the space between red (layer 2) and green (layer 3) to be filled in black. I thought the best way to do this was do an off-set of the green layer (#3) but that doesn’t seem to be working. Does off-set work for odd shapes like this example of a lightbulb or is is only for standard shapes? I’m hoping there is an answer for this that I’m missing. I believe there could be an answer by some form of weld or Boolean Union but I’ve not become proficient or needed to yet for things I’ve done.
Pictures and file included.
Offset is exactly what you want to use. Why do you think it won’t work? It does have to have a closed shape to work with. What happens if you set green layer to fill?
The problem lies with the inner bulb. It is not a closed shape. If you fix the open ends to make it a closed shape and put it on its own layer (black), it will fill. The breaks are at the base of the filament sticks. As they are also filled, you could remove the horizontal lines at the base of the filament sticks, then join the now open edges of the filament sticks to the open ends of the inner bulb. This would create a closed shape and immediately fill it.
There may be breaks on the horizontal line of the inner bulb as well, as one appeared when I performed the tests. Easiest method to determine that you have it fixed is to set the two bulb layers and the filament sticks to one layer, set to fill. When it is corrected, the entire inside of the inner bulb will fill, more or less the opposite of what you want.
Once that happens, set the outer bulb to black and the inner bulb to black and you should have your objective.
Very interesting. After I posted and played with it more I was able to get the same results as you showed. Just when I think I have mastered Lightburn, I find I know nothing at all… Thanks for your help.
Offset isn’t really the answer to this one, as the problem was a non-closed non-connected shape. Once the shape was corrected, the fill works as requested.
