Beginners' Questions Path Division Not Working as Expected

    I have these two circles and this rectangle. I have made the rectangle into a path. When I use path division it makes these weird shapes, I was expecting it to break into a border, and three inner pieces. Can you tell me what I'm doing wrong?

    Hi Zachiah,
    The circles are not closed paths. So there is an opening on the right side of each circle, the nodes are on top of each other.
    You can use the node tool (F2) and select the two nodes on a circle and join them with this button:

    After that, division will be more predictable, I hope.

    ________________________

    Perhaps when you created the circles, they were not closed?
    Next time you can use this button to close a circle:

    Make sure your circles are fully closed before you convert them to a path (this one is the user error part).

    When creating the circle, this means that the angles for start and end must be 0.

    As for the surprising length of the gap between the two nodes, that's due to a bug in Inkscape 0.92.4 (but is not a problem when you have a closed circle instead of an arc).

    Ha, posted at the same time, almost :)

    Hi Maren,

    Yes, it is daytime here. Netherlands/Germany.
    Well, Zachiah has his answer I think.

    i am running on an old laptop, a lenovo thinkpad t510, and do not need to know the components to tell you that it is bad.i reset it, and downloaded inkscape again recently, i don't remember from where.I wanted to make a fish logo, but my program ran into a problem, when i click path division, it doesn't break it into pieces, it transforms it into more weird shapes, and 50% of my drawing is gone( you can see when comparing the 1st and the 2nd pic).i made sure that all of the nodes are conected, but still it dissapears. i don't know if i can fix it, or should i install inkscape all over again?

    @Steph_corn . I have no clue what you're after looking at your 2 images. Can you be more precise please?

    i have no clue neither, it just cuts parts of the shapesΒ and combines the rest of them into one shape

    What do you want in the end? I can't even say what's before and after. Something like this maybe?

    First of all, make sure to have exactly two paths, not three.

    i wanted to devide the paths, and than make this kind of shape:

    but it uses the golden ratio, so i cant resize or draw over it, i need to make it perfect

    You can convert the circles to paths, add nodes in the intersections, split the nodes and reconnect them.

    Or... you put a full-color rectangle behind the circles, combine the circles to a single path, do Path > Division with circles on top, and then union the parts you want to keep (much faster).

    (May still require a bit of node editing if circles don't touch perfectly, but it's a 2 minute thing or less)

    It worked, thanks a lot

    I was trying to align circles and rulers with snapping without success - I'm under the impression it worked in a former version:

    Maren Hachmann Maren Hachmann @Moiniβš–

    It requires a node or a quadrant point on the object that you want to snap, apparently. There's a path effect, though, that would allow you to snap nodes together and create circles around them.

    (I seem to remember that there once was an option to only snap tangentially, but I cannot find that anymore - maybe it's gone?)

    No it's not gone; you find it inn Document Properties->Snap->Miscellaneous. But does just help with the BΓ©zier-tool as far as I can tell. I was just able to snap a guide where 2 circles are crossing each other - but the node-tool won't snap a partially circle to that guide here (anymore).

    Maren Hachmann Maren Hachmann @Moiniβš–

    Yes, quadrant points don't appear to snap to guides while drawing, only afterwards, when moving the whole object. The behavior is identical in 0.92.5, 1.0.2 and 1.1beta.
