What I want from python script, searching a workspace containing Geodatabases and feature classes(Iterate Feature Classes), then clip those by interested Area (polygon). the resulted clipped files most not empty. I tried to convert Model builder to Python script and added "If" condition to transfer not empty features to final geodatabase:

import arcpy
from arcpy import env
#script arguments
clip_Features = arcpy.GetParameterASText(1)
FeatureClass_clip = arcpy.GetParameterASText(2)

#Local variables:
Recursive = "true"
Name = "FeatureClass"
Feature_Class = "\\FeatureClass"
FeatureClass_Clip__2_= FeatureClass_clip

FeatureClass = arcpy.ListFeatueClasses("*")
#Process : Clip
arcpy.Clip_analysis(FeatureClass, Clip_Features, FeatureClass_Clip, "")
#Process: Delet Features
for fc in FeatureClass_Clip:
    if count1 <> "0":
       arcpy.FeatureClassToGeodatabase_conversion(FeatureClass_Clip, "")

I imported the script to toolbox and defined parameters, but script not ran because of clip raise error.

Try this thing. Here it works with gdb files. Make two input parameters: the first is *.gbd with feature classes you want to check, the second is clip feature class

import arcpy
import  os

from arcpy import env

#script arguments

gdb=arcpy.GetParameterAsText(0) #type - workspace
clip_Features = arcpy.GetParameterAsText(1) #type - feature class
out_gdb = arcpy.GetParameterAsText(2) #type - workspace

arcpy.env.workspace = gdb

#get feature classes full paths
#this thing will search only for feature classes in the root of gdb file, not in datasets

flist = arcpy.ListFeatureClasses("*")
list_to_clip = flist

#make feature layer of clip feature class

arcpy.MakeFeatureLayer_management(clip_Features ,"clip_layer")

#iterate through feature classes of gdb

for n in list_to_clip:
    in_fc = os.path.join(gdb, n)

    #check if selection contains features

    check = arcpy.Describe("f_layer")

    if len(check.FIDset)!=0:

        out_fc = os.path.join (out_gdb, (n + '_clipped'))

        # at this moment you can do whatever you want with your selection, i.e. clip, copy, convert

        arcpy.AddMessage("Layer "+ n + " clipped")



UPDATE: to use script with output gdb:

Added these strings:

out_gdb = arcpy.GetParameterAsText(2) #type - workspace

Changed the process of making feature layers: input layer:

for n in list_to_clip:
    in_fc = os.path.join(gdb, n)

output feature class (calculated with gdb set by user in [2] parameter):

out_fc = os.path.join (out_gdb, (n + '_clipped'))

changed method of calculating the selection (len("f_layer") will give the exact number of features in feature class if they are not selected):

check = arcpy.Describe("f_layer")

    if len(check.FIDset)!=0:
  • I think script needs a destination geodatabase to get as parameter! how can I re struct the script to transfer clipped feature classes to a new geodatabase?

  • @J.Sobhan sorry for long answer, check the code above I made some corrections, now you can use it with output gdb. Relace the text and add a parameter like Output GDB in Script Properties. Commented May 29, 2017 at 8:26
  • @ Pavel Pereverzev, I appreciate your attention and time to my question. I converted the script to the tool but an error happened " clip feature dataset exists! ..." I changed source workspace, clip feature, and output workspace, the error still persists.

  • @J.Sobhan you mean you converted it into pythonaddin tool or what exactly? Commented May 31, 2017 at 12:50
  • @J.Sobhan well, this script is made for *.gdb bases with feature classes. You can try to change type of arcpy.GetParameterAsText(0) to "Folder" and loop through shapefiles in folder Commented Jun 1, 2017 at 8:04
