I've been working recently on 3D printing TSP maps. I've included a pretty simple sample right here:

Zebra TSP Map

The issue is that when I try to manipulate this figure, it recognizes it as 25 separate sections. I thought that there may have been some node limit per object, but as it turns out, some of the sections were not properly joined (I only discovered this around 25000% zoom)

enter image description here

The end node shown is in the EXACT same position as the end node of the adjacent object not highlighted, but they are definitely different. (I can move each independently) I don't know how to join them, and the research I've done hasn't yielded much...I don't mind fixing it, but I don't know how.

  • beautiful graphic! - would you mind telling how did you produce this?

  • @msciwoj If I'm not mistaken, this is a Travelling Salesman Problem self-organizing map: diego.codes/post/som-tsp However, I have no idea why it looks like a horse, so I may be entirely off the mark.

You can join the two paths using node tool.

  1. Select both the paths using node tool.


  2. Select the two nodes at the joint and click on the "Join selected nodes" icon from the control bar as shown


Now the two nodes at the joint are connected to form a single node.

    You can use this technique for as many nodes as you want to join together. Just select all of them and click "Joint selected nodes" once. You don't have to do them one by one! Commented Jan 9, 2019 at 8:30
  • In case you have the nodes of the two pieces one over the other, just select with a a rectangle selection instead of trying to click on each node. Commented Jul 28, 2019 at 16:24
