I'm new to the graphical modeller of QGIS, and was wondering how to keep a line shapefile which has been edited and some of its parts deleted? For example, I have a country polygon that I have changed into lines using the vector > geometry tools > polygons to lines. The country investigated being a coastal country, I edited the line layer, split it, keeping only the coast line.
Then I use the SAGA tool to convert lines to points. However, when running the model from the beginning, it will transform all the lines into points, including the ones I don't need. Is there a way to keep the newly edited line layer in the model and then run the lines to points tool on it?
