Additional Information

The Maplex Label Engine first attempts to place labels in an area of free space (without any weighted features). If there is no free space available and a feature must be overlapped, a location with the lowest total feature weight is chosen. Use polygon interior feature weights sparingly. Often a boundary feature weight will suffice. Interior polygon feature weights discourage labels from being placed on the inside of the polygon, and the Maplex label engine will spend more time trying to avoid the polygon feature. Layers and label classes out of their defined scale visibility range are not passed to the placement engine as barriers, so their feature weight is not considered. If the feature weight must be considered even when the label class is out of range, include another label class that is unlabeled but still visible at the current scale. As long as the label class scale range includes the current scale, the feature weight will be applied even if labeling is turned off. Refer to Weights in the Maplex Label Engine for more information.
