arcpy mapping: getting the selected features of one data frame selected in another df

[jasonfargo]

does anyone have example code showing how to get the features that are already selected in one data frame to also select the same set of features that are in a different data frame?

Jason,

Here is the code you require, take note of assumptions and adjusted accordingly.

# Description: Passes selection from one DataFrame to another for the same layer. # Usage:       Designed to be run in Python Command line window. Code assumes layers are Shapefiles and a selection actually exists # Author:      Duncan Hornby # Created:     27/11/13 import arcpy   # Get map document and list of DataFrames, code assumes only 2 exist mxd = arcpy.mapping.MapDocument("CURRENT") l = arcpy.mapping.ListDataFrames(mxd)   # Get DataFrames df1 = l[0] df2 = l[1]   # Get layer from first dataframe and create a list of select FIDs layername = "yr89_clipped_water_as_polygons" # Change this to your layer name l1 = arcpy.mapping.ListLayers(mxd,layername,df1)[0] d = arcpy.Describe(l1) fids = d.FIDSet toselect = fids.replace(";",",")   # Get second identical layer in second dataframe and do selection l2 = arcpy.mapping.ListLayers(mxd,layername,df2)[0] sQuery = '"FID" IN (' + toselect + ')' arcpy.SelectLayerByAttribute_management(l2,"NEW_SELECTION",sQuery)
