Select open shapes not working?

[loather]

Hi folks,
I have a project I created through the use of a bunch of boolean operations. Somehow, some pesky unclosed shape got created. I don’t see it, I can’t find it, and I get a warning every time I preview or cut. Fortunately, we have the fancy, “Select Open Shapes Set to Fill” option which should obviate the problem. Problem is, it doesn’t seem to actually do anything I’m likely doing something wrong, but after futzing with it for a few minutes I decided I’d come ask the experts!

Screenshot of the project (yes, I stole the idea from that imgur post everyone saw a few weeks back)

When I click, “Preview”

This is the menu option that should make obvious what shape is to blame:

Nothing appears selected after following those steps. Even more odd is that it cuts properly, everything’s there, and there’s otherwise no problems.

Machine is a 65W Bosslaser LS-1416 with a Ruida RDC-6442, 400x350 mm bed, home upper-right. Source file attached for convenience.

Notice that the green-dot origin isn’t along the left edge of your file? Do a drag-select over there on that side and you’ll snag the ellipse in the file with a zero width. You can delete it, and I’ll put something in LightBurn to catch those.

You have a strange artifact in your file. Selected to show where it’s at. Basically, I deleted everything in the file, and the origin mark went to this location. I can select it, but can’t see it. If I delete that, the error goes away. For some reason, it doesn’t select with the Select open shapes, butt that’s where the issue is.

It’s an ellipse with a zero radius, so it produces a single vertex when converted to paths (which in itself is technically a bug - it should return nothing)

Since an ellipse is always technically a closed shape, the ‘select open shapes’ code misses it.

Wow, I actually found a bona fide bug. I was convinced I was just doing something wrong.

Thanks for helping me identify the shape causing this. I’ve since eliminated it and the warning has gone away.

Off-topic: Steve, what did you do to get the layout window to fill shapes like that instead of draw outlines like in my screenshot? I could definitely find that useful sometimes …

I don’t recommend leaving filled rendering on for extended periods - It’s significantly slower, and if you’re trying to draw lines they won’t show up until the shape is closed.

No, for the general use case i think wireframe is what I want. This is more of a real-time preview when I move completed shapes around and I’m not immediately sure what it’ll do on a fill layer.
