Cómo agregar una leyenda a la capa en ModelBuilder

¡Queridos todos!<\/P>

<\/P>

Estoy intentando agregar una leyenda a la capa en modelbuilder. Las páginas de ayuda dicen que necesito usar la herramienta "Apply Symbology From Layer". He guardado mi Capa de Simbología pero no contiene mi leyenda (según entendí, una leyenda solo puede guardarse en un archivo de Mapa). ¿Podrían explicarme cómo hacer esto correctamente?<\/P><\/BODY><\/HTML>

If I understood correctly, you want to add legend with model builder.Apply Symbology From Layer extracts Symbology from a layer ( which is a layer you prepared before) to another layer which does not have symbology. 

As far as I know , there is no tool to include legend in model builder but you could create a script "to add legend" in python and make a tool with that script. Then you can add it to your model. Here same code you can use to create layer from shp and add sybology.

import arcpy

symbologyLayer=r"C:\.....\sembology.lyr"  # if you want to assign same layer format all the time this can be a path to your symbology

LabelExpression="[Fieldyouwantolabelwith]"  #if you want label you can make it parameter if not you do not have to use this label parts

K_shp= arcpy.GetParameterAsText(0)  ### your shp file  you want to assign symbology

## those above will be your parameters

mxd = arcpy.mapping.MapDocument(r"C:\......\my.mxd")

#or mxd = arcpy.mapping.MapDocument("CURRENT")

df = arcpy.mapping.ListDataFrames(mxd)[0]

arcpy.MakeFeatureLayer_management(K_shp,"Layername")

lyr1= arcpy.mapping.Layer("Layername")

arcpy.ApplySymbologyFromLayer_management (lyr1, symbologyLayer)

lyr1.labelClasses[0].expression = LabelExpression

lyr1.showLabels = True

legend = arcpy.mapping.ListLayoutElements(mxd, "LEGEND_ELEMENT", "Legend")[0]

legend.autoAdd = True

arcpy.RefreshActiveView()

arcpy.mapping.AddLayer(df, lyr1, "BOTTOM")
