Glue nodes of one object to nodes of another

[Intanjir]

Although only end nodes can be merged, it would be nice
to glue arbitrary nodes between objects together. In
this way a path might seem to fork even though SVG only
allows simple paths. If the curvature at each node was
shared, objects could also seem to share entire
segments, even though each object would actually have
its own copy of the segment. Although this would create
redundancy in the SVG file, it would aid editing. When
saving to Plain SVG, any redundant subpaths could be
removed.

Carl, can you please review this and lots of other snapping
bugs/rfes and close those you took care of?

Thank you for taking the time to report this bug and helping to make Inkscape better. You reported this bug a long while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest Inkscape release? Thanks in advance

I would like to get the priority a little higher. I really could need this feature. See also here

This would be extremely useful in technical drawing and in cartography where closed paths often conceptually share significant segments.

In essence we need to be able to make a node a member of more than one path but this is potentially complex with beziers because there would then be nodes that end up linking to three (or more) other nodes.

If this worked it would save me many hours tweaking region boundaries on maps or related gui object borders.

This feature is more interesting and powerful than you expect: once you can make objects dependent on each other by gluing them, you get geometric analysis. So you can do fun stuff like this:

You can move a node and the rest of the diagram will morph to accommodate it. More elaborate diagrams result in more fun. It's very useful for geometry in math olympiads, where objects are glued in dependencies that are 20 or 30 objects deep.

Any gluing model would basically be an acyclic directed graph of dependencies.

Isn't this solved now by the 'Attach path' LPE?

Closing because [.this can be done with 'Attach path' LPE]
