<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Courier New"">I had to test it out too, having wanted to do such things in the past and had to click on the midpoint to add anything for each new point (then drag to where it needs to be).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Courier New""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Courier New"">Adding to the END of line segments works perfectly fine when the + is selected. Is there a similar function where any other point/vertex can be started from for both line and polygons
and just click where you want the next vertex to be and not have to create and then move each new one?<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Courier New""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Courier New"">I think that is what people are asking about/wanting – but I may just be extra confused now. I didn’t know about clicking the + at the end of lines to continue those, so that was
useful to find out. Now just need to know if there is something exactly the same for every other vertex, not just ends of lines. :D<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Courier New""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Courier New"">But perhaps that + in the middle of polygon segments is supposed to indicate the same thing, just that it doesn’t work the same way as at the ends of lines.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Courier New""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Courier New"">Also just noticed that the behavior of the central + when editing vertices of lines behaves differently than for polygons. On polygons once you click the + the point is stuck there
(and you have to click it again if you want to move it), but between points of lines when you click the + it remains selected and moves with the pointer until you click again.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Courier New""><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="font-size:12.0pt;font-family:"Courier New"">It would be nice to be able to Ctrl/Shift/Alt/(something)-click that + between vertices and then continue adding to anything (line or polygon) until there is a right-click.<o:p></o:p></span></p>

<p class="MsoNormal">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.

<p class="MsoNormal">No, You don't need to reselect: Given an existing line, take the vertex tool, move close to an end point, click on the '+' and you can extend it with as many segments as you wish (<a href="https://docs.qgis.org/3.22/en/docs/user_manual/working_with_vector/editing_geometry_attributes.html#basic-operations">https://docs.qgis.org/3.22/en/docs/user_manual/working_with_vector/editing_geometry_attributes.html#basic-operations</a>

<div>
<p class="MsoNormal">The issue here, and I confirm Andreas' first message, is that the vertex tool ignores the tracing option, you need t click every new vertices.<o:p></o:p></p>
</div>
<div>
<p class="MsoNormal">Another issue I saw is that I spent a lot of time to find the tracing button: it's available on the snapping toolbar, but not on the snapping Options widget which opens (and I didn't enable the toolbar). I still have issues to understand
why we need two interfaces for these options, with tools that are in one place and not in the other.<o:p></o:p></p>

<p class="MsoNormal"> 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.<o:p></o:p></p>

<p>Hi,<o:p></o:p></p>
<p>When I am extending an existing line with the vertex tool (by enabling the vertex tool and clicking on the small "plus" symbol), can I then still activate the "tracing" functionality to follow along other features?<o:p></o:p></p>
<p>If yes, I haven't found out how - any hints would be appreciated a lot!<o:p></o:p></p>
