I'm modifying the existing water pipeline network. Sometimes I have information that the pipe from the beginning to the 125meter has a diameter 63mm after that point it has a 100meter -diameter 50mm and the rest of it 32mm. I need to split that 1 pipe into 3 pipes 125meter, 100meter, and the rest of what was left (to give different diameter attributes(63,50,32)). And I also need it to be modified in the same shapefile. Advanced digitizing and v.split don't work in this situation.

And I also need it to be modified in the same shapefile. Advanced digitizing and v.split don't work in this situation.

I want to split this line from the beginning to the 125meter by trace. the line has multiple angles. Advanced digitizing doesn't work in this situation.

for instance,I want to split this line from the beginning to the 125meter by trace. the line has multiple angles. advanced digitizing doesn't work in this situation.
