I have tried this many time, but no matter how many path that I use, the aresult is the same. There is a Gap in Voronoi Diagram like this

Is there something wrong with my object, or is the result look normal to you all? How to fix the gap?

That looks odd. I usually get more like this:

Please share an example svg that has the issue.

Here is the file

Edit: Can you tell me how to post the file, not just image into this forum's chat? Cause I have tried to share via Google Drive, and there is only image

Maybe this: "For a set of points on the same line there is no Delaunay triangulation (the notion of triangulation is degenerate for this case)." (Wikipedia)

For security, some file formats are forbidden to attach. Images and some  other filetypes can be inline, thumbnail or attachment.

Where is "Tutorial #14" from?

Hi. I think the problem is that there are two overlapping circles in two places. Delete them. I leave a small video.

@mrks9 Hi Marcos, i check your file,but the file is corrupted

I don't know what's wrong with my videos, maybe because I'm on Linux and windows doesn't recognize them. In the upper left corner and in the upper right corner you have duplicate circles. Delete them.

Videos work for me in Chrome.  (Maybe because I have ffmpeg installed? IDK)

Nice catch Marcos!

@TylerDurden I have delete few objects that set too close to other, and do the Voronoi Diagram. Here is the result

Also, I want to ask you about "For security, some file formats are forbidden to attach. Images and some  other filetypes can be inline, thumbnail or attachment.". Do you mean for security of inkscape or security policy from Google Drive?.

And for the tutorial part, it is because I learned Tutorials from Logo By Nick videos and this is 14th tutorial i have learned from him, so yeah that's where Tutorial #14 come from.

@mrks9 Hey it worked, here is the result

From your file, I have only deleted the two circles that I was telling you about and this is the result.

@earvinwilliams96 Great!

Oh yeah, I hate it when you duplicate objects and then, you don't realize you have duplicate the object before,so you have three object stacking in the same position, get to be more careful about that next time.... Anyway thank you for the help @mrks9

And thank for you too @TylerDurden

It's possible the extension live preview is duplicating objects. I might have seen that happen.

@TylerDurden I have made a test and in my case there is no duplication of objects, it works fine.

@TylerDurden I think it's because i accidentally duplicate it without realizing it had been done before, although there is extension that i know, can make duplicate of the objects just like Interpolation extension
