I think I am not understanding how the setting under “Connections” “Allow connections from lines” works. I thought if I had that enabled, another line I drew would ‘lock’ onto a nearby line node (mainly the end node). That would make it easier to extend a line without having to drag the end node to the far end of the drawing and start adding nodes along the desired path. I find that it doesn’t seem to do anything. Only when I check “Allow connections to other objects” can I get two lines to connect.
I am not using Guides (both Alignment and Distance Guides are turned off) nor a snap to Grid.
What am I missing?
