Shapes are not stick to each other seamlessly (a gap between shapes)

[midfun]

Good day,

I recently decided to try to create a minimalistic logo in Inkscape, with only from triangles in my case. For this, I created an axonometric grid. Working in Inkscape was a little less convenient than in the usual AI, but everything was fine as long as I did not turn off the grid. It turned out that the shapes (triangles) are not ideally stick together, but have a small gap, as if the grid line had a real thickness. Then I tried to repeat this without a grid, but there is still a gap.

Maybe there is a magic settings to fix it? I'd tried to search it, but no result. There was one close issues (http://www.inkscapeforum.com/viewtopic.php?t=16453), but it seems TS choosed another program in the end.

Please, help.

Welcome to the forum!

Yes, the triangles are perfectly aligned one to another.   This is a known problem caused by anti-aliasing.  Many graphics programs have this problem.  Here are all the known solutions for Inkscape:  https://inkscape.org/en/learn/faq/#theres-seam-or-artifact-between-adjacent-objects-sharing-same-border-or-between-patterns  My favorite is the Stitch filter, but there are several others.

Anti-aliasing and compositing together produce the tendering gap issue, here is an explantion.

I prefer overlapping the shapes -filtering doesn't transfer to a full vector pdf, although it can produce a good rendering on opaque shapes.

Thank you for your helpful answer.
To be honest, this is the first time I've face to this kind of problem.

Actually, Stitch filter real works, but am I right that now I have to add a "Stitch file" to each project? Like an injection of the vaccine for this issue?
Union/Combine also works, it's OK to combine a shape after design.

Of course, I would like to see this problem never appeared at all — the "stitch filter" is not a reliable solution, 'cause it modifies the objects themselves, which can lead to unexpected problems in future. And Union/Combine can't be used at the design stage.

I realised the problem a few years ago.

Ever since, using overlapping -here is a collection of images with an overlapping structure I've drawn. Sometimes it can get real tricky.

I probably should explain that I like to suggest the stitch filter, because it works under many different circumstance.  But overlapping the objects by a couple of pixels is probably the best solution.

Or the other thing you could easily do, given the simplicity of those particular artworks, is use the Pen/Bezier tool, perhaps with guidance from grid or guides, and snapping; draw a diamond shape as a whole, rather than make it out of 2 or several triangles.  In my opinion, that is the best solution, in this case.
