I am having a really hard time digitizing roads in a map for an assignment in my GIS course. I follow the steps, I open editor, snapping, I open a window to create a new feature. But when I start digitizing, the lines I draw keep disappearing after I double click on them or click finish sketch. I use the auto complete polygon construction tool because I am not making an enclosed polygon I am just making lines along roads.
Does anyone know what issues might causing my lines to disappear and how I can fix them?
