I have created 16 label classes and I want each label class placement property to be on the line. Two of the label classes are labeling above the line with the placement property set to "on the line". On the Conflict Detection tab I have buffer set to 0 for all label classes. For the 2 label classes in question I have label weight set to high and feature weight set to none for fastest drawing speed. Does anyone have a recommendation to get the two other label classes to label on the line?
