I am trying to join to linestrings at the intersection in the red circle below in my project file but it says the 2 lines support joining but cannot. Can anyone help with this? I am currently using version TBC 5.30
In order to join two linestrings using this method, the end points must be within 0.0001 m of each other. Can you confirm that this is the case?
I would try to change the option from All selected Lines to Two Lines. When you use the two Lines option it ask if you would like to fill the gap (mostly there is a gap like James wrote). When you choose All selected it just connects the Lines which are perfectly on the same spot.
Let me know if it works!
