I am making a logo from an existing graphic, I found it easier to trace the image on my iPad pro with my pencil, drag it into Inkscape and then edit nodes.  It is pretty good so far but there are two lines that will not connect together, however how I try.  I cannot think how to explain the problem, it would be easier to show, but I am unsure how to get the file up onto here.

Inkscape is running on iPadOS?

Nodes: Select the and hit "join selected nodes" should work.

Thank you - I don't know how I missed that.

Technically speaking you don´t have  paths but color filled shapes because of the dynamic stroke. But there´s an easy fix by dragging the corresponding nodes on each other - so there´s an overlapping and then Path->Union will work. Just in case you want to fill the inside with color you´ll run into the next hurdle because you can´t; same reason as before. But you can go Path->Break Apart - now you can raise the inner parts and apply a dedicated color.

Fantastic - I knew there would be a sensible reason for it - just not experienced enough to know what.  Thank you so much for this - I couldn't think of an easy way to bring in the original image and do the whole thing in Inkscape because when it is traced it has hundreds and hundreds of nodes, which I started editing by hand and gave up after a a few hours.  It is really so I can laser engrave it onto various items, so this should work perfectly.

Is there a way of downloading the above video to keep?

Ideally, should I start again?  Because I would really like to have all the lines uniform and easily manipulated.

Here´s a grid for you; take the Bèzier-tool and enable a decent snapping and click your way away in a few seconds: To move nodes along a given angle hold shift+ctrl keys down. Have fun.

Thank you again - I will have a go and let you know the results.
