I have a question about my model which is quite complex.
I have two types of line INPUT and the model will not be executed unless one of the line INPUT is empty. The problem is with a tool '
Snap points to lines' (logically - because there are no lines and points neither).
The question is, if there is some way with Graphical modeler to use a condition like
IF one of the line INPUT is empty THEN 'freeze' this branch of model, but continue with the second line INPUT
I guess the best way is to turn the model into a script and here I can manage better the conditions. But I am not really PRO in Python so anybody can give me a hand?
