The out-of-the-box labeling engine does a fine job with forcing all labels to display despite of overlap. The same cannot be said of Maplex.
I have a polygon layer obtained from the Ontario Provincial government which is solely used for labellings geographical features. (Geographic Name Extent) This is a polygon layer that contains all known "Geographical Name" features along with attributes such as various categories and names in English and French. (Federal government CanVec/NTDB uses a point layer for a similar purpose)
I have a layer that I maintain in which i store the Label schema; all the label 30 definitions and symbols. I simply just import the label schema and turn the labels on. (export and manually correct if needed) I am in the process of updating this layer to work with the Maplex engine but I am unable to place all the labels.
- I have 30 label classes
- each class is defined by a simple SQL query
- each class has a different symbol
- each class has different placement properties depending on type
- all label classes are set to "Never Remove (Allow Overlap)"
- classes with highest priority have a weight of 1000, lowest priority 0
Still many labels are not placed.... Any ideas?
EDIT: I moved the layer to an empty map and I can confirm that when Maplex is off everything is labelled. Turning Maplex on un-places all SMALL POLYGON labels. However, if I zoom extremely close the label appears. I am beginning to feel like Maplex might have been a waste of money. I tried to bring in the layer in question from scratch and creating just one default label class using Maplex - turned on "Never Remove" with same results. All small polygons indicating a location of a town or a bay will not label until over-zoomed. A bug?
EDIT 2: It gets better! I exported all to annotations and out of 1002 features only 429 annotations were created. (Out of which 4 are unplaced) 573 annotations Which I was hoping to "place" manually are missing.
