Boolean function issues

I have worked around most all of my issues when drawing within Lightburn, as least at my beginner level. But I can not connect the line, shown dotted to the line it runs into to. I’ve tried everything I can think of. So, obviously I’m missing something. I’ve include the file and the image of where my problem lies…
Any help would be appreciated.

LightBurn doesn’t let you do T-junctions like that, because the result would be ambiguous.

For example, if I draw a circle with a line through the middle like this:

If I set that to “Fill”, which half should be filled? Top, bottom, or both?

If I make these two shapes instead (shown side by side for clarity) then there is no ambiguity:

LightBurn needs closed areas to fill them.

Thank you…
