I am trying to write a python script and am stuck on the first obstacle.
I want the user to select features in ArcMap and then use these selected features in a python script.
Is that at all possible and does someone have a code example?
The code that I have now uses all the features instead of just the selected ones. Please see code snippet below.
arcpy.MakeFeatureLayer_management(pipes,"pipeslyr")
arcpy.SetParameter(0,"pipeslyr")
pipesnew = os.path.join(ws,"pipesnew")
arcpy.CopyFeatures_management("pipeslyr", pipesnew)
Answer
arcpy.CopyFeatures_management works like right-clicking on the layer > export data > selected features. Then you can make the layer from that exported selection. I'd do this "in_memory" so you don't have deal with overwriting each time you run the script.
import arcpy
from arcpy import env
arcpy.env.workspace = "in_memory"
selected_features = "The Feature Class with the selection.shp"
pipes = "the new feature class to convert to a layer"
#this will create a new feature class from the selected features but will do it In Memory
arcpy.CopyFeatures_management (selected_features, pipes)
#Now do all the other stuff you want like convert it to a layer and work with it
arcpy.MakeFeatureLayer_management(pipes,"pipeslyr")
The selection would need to be made before this is run.
