[Qgis-user] Line dissolve

[Nicolas Cadieux]

Hi,

Yes, Harrissou,
That does not work with lines unfortunately. I tried multiple times with different combinations.  It works with polygons when common borders need to be dissolved. I did see a merge function but did not find the line_merge plugin in  the repository. I figured it was QGIS2 and had been dropped.  Do you have any info of this?
