{{Note | An alternative solution to change colour of the polygons is to use [[Add a Poly Property | Poly Property]] that make makes it possible as well to distinguish between polygons that belong to the same report.}}
If you would like to change the existing symbology, you need to use [http://desktop.arcgis.com/en/desktop/ ArcGIS software ] to update IMSMA.mxd which is located in ''C:\IMSMAng\server\gis\maps'' folder.
In {{IMSMANG}} version 6.0 it is not possible to change the IMSMA.mxd to show different colours of the polygon based on Type, Status, etc. i.e. it is not possible to have red for Open, Orange for Worked on and Red for Closed. But it is possible to change how to polygon looks like in {{IMSMANG}}.
==Steps==__NOEDITSECTION__
As an example, Land by Status theme will be used. The use case could be that the users wanted to have the polygons filled with diagonal stripes instead of filled solid.
<ol><li>This is how the [[Map Display Window]] inside IMSMA looks like before any changes on the .mxd file:
[[Image:Polygon_symbology0.png|400px|center]]
<div align="center">
'' IMSMA layer Land - by Status''
</div></li> As example <li>Open IMSMA.mxd with ArcMap and go to Land by Status will be usedlayer. Here the users wanted to have Double-click on the polygons filled with diagonal stripes instead of filled solidlayer or right-click and choose Properties.

<li>In the IMSMA client (if your configuration is client/server then start the IMSMA client on the server computer) go to File, → Import, → Map. </li>
<li>Import the background map which will be merged with the updated IMSMA.mxd. </li>
<li>Verify in Map Display that the changes are applied.
