I am trying to extract lines to a new layer that don't fall 100% within a polygon. I want to leave out anything that does. I can not get extract by location to work in the modeler, it does work when run by itself. Is there another option or some information on how the plugin works.

  • What's wrong with Extract by location when you select predicate 'crosses'? This gives me all linestrings of wich less than 100% fall into the polygon. Or do you want linestrings that are totally outside the polygon too? And didn't we just discuss Select by location in gis.stackexchange.com/questions/256981/…? I thought this works in modeller when setting parent algorithm? – Jochen Schwarze Oct 5 '17 at 8:03
  • The parent algorithm isn't working for extract by location. This is a different project. It does work outside the modeler but for some reason I can't get the model to produce a result. I've added an image of the model as it currently stands. – brink Oct 6 '17 at 22:25
  • Ok, I figured it out. It is the parent algorithm but only specific ones. Why isn't there better or complete documentation on using the native plugins? It eats a lot of time having to do trial and error or waiting for an answer on stack exchange just to get something to work. – brink Oct 7 '17 at 0:36
