I have overlapping lines in my layer and want a total length of the visible line without the overlapping part.
I have two lines
First one goes A-B-C
Second one is B-C-D
How do I get the length from A-B-C-D?
If the lines overlap exactly on top of each other then I would suggest dissolving them or merging them into a single line in a separate layer and getting the length of that line using the $length function in the field calculator.
