Centering a label in polygon

ChrisBridges2 — Tue, 19 May 2015 21:12:26 GMT

Hi,

I have a polygon of township sections and have the label set to show the section number. As you pan the screen the section label moves to where it is visible on your screen (if that section is visible). What I want to do is have the label stay centered in the section, even if the center of the section is not visible. I tried using the label manager, however my only placement options for the polygon are "always horizontal, always straight, try horizontal first, then straight and only place label inside polygon". I was thinking there is a way to force it to stay in the center, no matter what part of the polygon is on the screen, however I can't seem to find it.

Any help in the right direction is appreciated!

If you haven't turned on Maplex labeling, do so. Then, in Placement Properties, enable Place label at fixed position within polygon, and set Internal Zones to the centre zone = 1.

Darren,

Thanks, that did it! I had forgot to turn on Maplex labeling.

Maplex labeling is definitely the way to go! I can't recommend it enough. I thought I had read somewhere about needing a higher license level though, but of course I can't find anything about it in the help files now.

I think that used to be the case, but it's included out-of-the-box for all, now.

Oooh, I just found this super handy description of all the Maplex options. You might find it useful: https://www.esri.com/library/whitepapers/pdfs/maplex-for-arcgis.pdf

Hi Sephe,

Please note that the white paper is from 2009!

you can find the most up to date Maplex doc online

I confirm what Darren said - Maplex used to be a separate, but now it comes with all versions of ArcGIS. I'm tempted to say the change happened at version 10.1, but I could be wrong.

The biggest challenge with Maplex now is remembering to turn the darn thing on for each of your data frames (the default is "Standard Label Engine").

Hi Chris

you can set Maplex Label Engine as the default label engine

Setting ArcMap options—Help | ArcGIS for Desktop

At ArcGIS Pro it is automatically the default

Maplex has been around for a while - from a separate product, to an extension, to an included label engine, to the default label engine!
