I remember that I read somewhere about the curvature being lost after rerouting - it said that when the path is recalculated, it recreates it with the least possible nodes, therefore any custom nodes that were added to accomplish the curvature are deleted and it recreates the path just from 2 nodes ...

OK, I'm not even able to make curved connectors, the curvature is lost after moving the object and rerouting, I've come to the conclusion that Inkscape is currently not even remotely usable as a diagram editor and the "connector tool" is there essentially just for show. I'm not able to use...

I've added a comment to existing bug report, this is a known issue at least for a year from 2015-04-22, shame it hasn't been fixed yet

Regarding the "convert to symbol" suggestion - it actually stops working also for the switch when I do that weird!

Yeah, the implementation of connector tool seems to be pretty poor, that's really a shame because I would like to use an open-source diagram editor but there is not really a good one - Inkscape looks like ideal framework to achieve this use case, I do not understand why so little emphasis is put on ...

argh, it does work as I originally described it (should have made the icons transparent from the start), the connection point for red router changes according to position and the blue one is always to the center

OK, the behaviour keeps surprising me - so it DOES work correctly for the switch shape, I connect it to the center, it binds and the line actually ends at the boundary, this is NOT working with the router shapes. I've made all shapes transparent to make it more obvious. Could this be a difference be...

Thanks for the suggestion but that (apart from being an ugly hack:) would mean I'd have only one connection point per shape and every time I'd like to connect to a different place I would have to ungroup, resize the transparent box, group again and reconnect ... that kind of defeats the purpose of u...

Ah, I see - the line always goes to the center, it depends only on the Z-order of the elements whether it is visible or not - then the question is, is it possible to define custom attachment points and make the connections to "stick" to them? Because now if I add styles to the line endings...

I've attached a sample file where you can experiment with the connections - the switch shape behaves correctly and the lines end at the switch boundary, however the router shapes behave each differently - the blue one is attached at the center at all times but the red one changes the attcahment poin...

Hi Inkscapers, I'm trying to use Inkscape to draw network diagrams (and schematics in near future) and I've come across a few issues, it would be great if someone could help to sort them out. I was trying to use stable version, but found out that in trunk there is addition of "cusp nodes" ...
