Andreas, You’re not along with this type of problem. I’ve run into the same thing with some of the ArcTools for (Auto)Cad, where when editing an imported feature, the attributes from the DB get destroyed. Supposedly fixed in recent releases, but our admins haven’t caught up with the new releases yet.

Think Before You Click: This email originated outside our organization. Hi Simon and Nicolas, Yes, that was our idea, too - to merge two or more lines that share their start/end vertices. But unfortunately, this doesn't work for us, because we edit in a very complex data model and QGIS doesn't preserve feature Ids when merging features --> all of our DB relations would then fail. See https://github.com/qgis/QGIS/issues/47629 I asked our commercial support provider to hopefully fix this issue ... then we could go the "merge route".

Hi, To my knowledge, when using the vertex tool, you click on the last node and then, you can extend it once. I think you need to reclick the last node again if you want to add a new point. I don't do much vectorizing lately and in the past, used AutoCAD to do it. There must be some other way of doing it. Maybe there is a shortcut or something like the shift key we need to use. I would check the user manual to see if there is an option under the vertex tool. I see that lots of new tools have been added lately making QGIS a good contender for tracing. I guess you could just create a new line and then merge both together. Just my grain of salt...

If yes, I haven't found out how - any hints would be appreciated a lot!
