You can use this code: import arcpy fc_in = r"C:\Forum\test.gdb\Polyline_chord" fc_out = r"C:\Forum\test.gdb\Polyline_straight" sr = arcpy.Describe(fc_in).spatialReference lines = [] with arcpy.da.SearchCursor(fc_in, ("SHAPE@")) as curs:     for row in curs:         polyline_in = row[0]         polyline_out = arcpy.Polyline(arcpy.Array([polyline_in.firstPoint, polyline_in.lastPoint]), sr)         lines.append(polyline_out)     arcpy.CopyFeatures_management(lines, fc_out) Kind regards, Xander ...

I probably would not use the Merge tool for this. Especially if you are not interesting in the attributes (only geometry). You could probably do something like this. Please not that I did not run the code, so be careful... ... but if it works it will: create an empty output featureclass (which should not be written to the folder that is being searched) searches for featureclasses of type polygon in the folder and all subfolders use a search cursor to obtain the geometry and insert it in the output featureclass import arcpy import os arcpy.env.overwriteOutput = True # settings basefolder = r"C:\Forum" fc_out = r"C:\Data\myFGDB.gdb\myResultingFeatureclass" sr = arcpy.SpatialReference(102100) # specify the correct WKID! # create the empty output fc (outside the basefolder!) fc_ws, fc_name = os.path.split(fc_out) arcpy.CreateFeatureclass_management(fc_ws, fc_name, "POLYGON", spatial_reference=sr) cnt = 0 # start a da insert cursor with arcpy.da.InsertCursor(fc_out, ("SHAPE@")) as curs_out:     # create a list of all polygon featureclasses in (sub)folders of the basefolder     walk = arcpy.da.Walk(basefolder, datatype="FeatureClass", type="Polygon")     # loop through featureclasses     for dirpath, dirnames, filenames in walk:         for filename in filenames:             # construct the absolute name to input featureclass             fc_in = os.path.join(dirpath, filename)             # for shapefiles (but also coverages)             desc = arcpy.Describe(dirpath)             if hasattr(desc, "workspaceType"):                 if arcpy.Describe(dirpath).workspaceType == "FileSystem":                     # start search cursor and insert features into output featureclass                     print "Processing featureclass: '{0}'".format(filename)                     with arcpy.da.SearchCursor(fc_in, ("SHAPE@")) as curs_in:                         for row in curs_in:                             cnt += 1                             if cnt % 1000 == 0:                                 print " - Inserting output feature: {0}".format(cnt)                             curs_out.insertRow((row[0], )) del curs_out, curs_in, row A simple enhancement could be to add a field to the output featureclass (text) and write the source shapefile name to the field. There is no check to see if the coordinate system coincides with the output featureclass. Also other polygon featureclasses like coverages, if present, will be included in the result. ... View more
