+This page is one of the !MapGuide Community CodeSamples.  Visit the CodeSamples page to view more!
+
+This sample script contains a series of utility functions to batch update a series of Layer Definitions in a folder to conform to a specified minimum/maximum scale range.
+
+=== How to use this script ===
+
+ 1. Launch MapGuide Maestro
+ 2. In the '''IronPython''' console, click '''Run File'''
+ 3. Browse to '''scale_ranges_utils.py''' and click '''Open''' to load this script
+
+Once loaded, you will have the following functions available for you to use from the IronPython console:
+
+{{{
+#!python
+def FixScaleRangesMinMax(conn, folder, min, max):
+    """
+    Modifies the first scale range of all Layer Definitions under the specified folder to the specified
+    minimum and Mmximum scales
+    """
+def FixScaleRangesZeroToMax(conn, folder, max):
+    """
+    Modifies the first scale range of all Layer Definitions under the specified folder to the specified
+    maximum scale. The minimum scale is un-set (ie. Set to 0)
+    """
+def FixScaleRangesMinToInfinity(conn, folder, min):
+    """
+    Modifies the first scale range of all Layer Definitions under the specified folder to the specified
+    minimum scale. The maximum scale is un-set (ie. Set to infinity)
+    """
+def FixScaleRangesZeroToInfinity(conn, folder):
+    """
+    Modifies the first scale range of all Layer Definitions under the specified folder to [0, Infinity]
+    """
+}}}
+
+To modify all layers under {{{Library://Samples/Sheboygan/Layers/}}} to have a scale range of 50 to 12000, you would run the following snippets in your IronPython console. This assumes a session with only one active site connection:
+
+{{{
+
+>>> conn = app.GetConnection(app.GetConnectionNames()[0])
+>>> FixScaleRangesMinMax(conn, "Library://Samples/Sheboygan/Layers/", 50, 12000)
+
+}}}
+
+This will output something similar to this:
+
+{{{

+}}}
+
+=== Limitations ===
+
+This only operates on the first scale range it finds of each Layer Definition in the folder you specify.
