Objects borders not perfectly aligned

Postby zAxny32 » Thu Dec 27, 2018 9:50 pm

Hello all,
I'm drawing a simple logo for an app and I noticed that some edges are not perfectly aligned even though I've enabled snapping to the grid (I used the axonometric grid). This problem can be noticed both from Inkscape and from GIMP, what could be the cause? I looked in the manual and in this forum but I didn't find anything similar. I'm attaching the svg file and the rendering from GIMP. Thanks in advance.

The original file. You can see that there is a red line between borders of objects.

Hi.
From my experience you need to enable one additional snapping feature to let points snap to grid/each other:

It looks like the nodes are aligned, but not snapped to the axo grid - despite the cusp snapping being already enabled.

Likely the issue is anti-aliasing artifacts when rendered to bitmap or by screen renderers. Vector objects with mating lines cannot be perfectly reproduced in pixels.

If paths are not required for cutting (e.g. vinyl signs, screens for printing, etc.) I'd overlap shapes a bit like shingles.

Have a nice day.

I'm using Inkscape 0.92.2 (5c3e80d, 2017-08-06), 64 bit win8.1

The Inkscape manual has lots of helpful info! http://tavmjong.free.fr/INKSCAPE/MANUAL/html/

Ok, I was able to fix my problem using that snapping feature and overlapping a little the objects where it doesn't work. Thank you for your help!
