How can I add a feature class (shapefile) to the current map doc using arcpy.mp (Python 3)?

DeanMirabito — Tue, 15 Aug 2017 20:12:33 GMT

I am writing a script tool to be used in ArcGIS Pro. The script tool performs some geoprocessing and saves its results to a folder. What I would like to do is add the results from disk back to the current map document. Basically, I am looking for the equivalent to the below for arcpy.mp in Python 3:

import arcpyfrom arcpy import env # get the map documentmxd = arcpy.mapping.MapDocument("CURRENT")# get the data framedf = arcpy.mapping.ListDataFrames(mxd,"*")[0]# create a new layernewlayer = arcpy.mapping.Layer(path_to_shapefile_or_feature_class)# add the layer to the map at the bottom of the TOC in data frame 0arcpy.mapping.AddLayer(df, newlayer,"BOTTOM")

I need to add a shapefile, not a .lyrx file. Is there a way to do this with arcpy.mp? I have been looking everywhere.

Maybe this could help you?

Hi Johannes,

Thanks for the link! It is helpful, but it does not address how to perform the operation with the arcpy.mp module. I have used the arcpy.mapping module in the past, but now I am on ArcGIS Pro. It seems like some of the changes from mapping ---> mp have made certain operations very difficult! It is mind-boggling to me that it should be so hard to add a shapefile from disk to the TOC.

Sorry Dean, I don't use Pro ... overread that ...

shp_path = # path to shape file

aprx = arcpy.mp.ArcGISProject("CURRENT")
map = aprx.listMaps()[0]  # assumes data to be added to first map listed
map.addDataFromPath(shp_path)‍‍‍‍‍

Joshua, thank you so much. This is exactly what I needed. The .addDataFromPath method is a lifesaver.

And this works for adding feature classes, as well. Thank you.
