Copy attribute fields from one feature class to New output feature class

Question

I have the following script - it creates lines from two points feature classes, Both point feature classes have a field # that identifies the center point ID to relate them. I would like to modify this script so I can I get all the fields from the related points relfc to spiderfc # Description: Creates spider diagram lines from two point feature classes. # Note: You need one point feature class for the center points and another # for the related points. Both point feature classes must have a field # that identifies the center point ID to relate them. # --------------------------------------------------------------------------- # Import modules import arcpy # Local variables cenfc = r"\GIS\starburst.gdb\CenterPoints" cenfld = "SiteID" relfc = r"\GIS\starburst.gdb\EV102218" " copy all fields from here relfld = "USER_SiteID" spiderfc = r"\GIS\starburst.gdb\Spider" # to here # Read in the ID values and coordinates of the center points print "Reading in center point IDs and coordinates..." cendict = {} for row in arcpy.da.SearchCursor(cenfc, [cenfld, "SHAPE@XY"]): cendict[row[0]] = row[1] # Read in the ID values and coordinates of the related points and create line geometry objects print "Reading in related point IDs and coordinates..." linelist = [] for row in arcpy.da.SearchCursor(relfc, [relfld, "SHAPE@XY"]): relxy = row[1] cenxy = cendict[row[0]] polyline = arcpy.Polyline(arcpy.Array([arcpy.Point(cenxy[0], cenxy[1]), arcpy.Point(relxy[0], relxy[1])])) linelist.append([row[0], polyline]) # Setup line feature for spider lines print "Setting up line feature for spider lines..." sr = arcpy.Describe(cenfc).spatialReference tempfc = "in_memory/tempfc" arcpy.CreateFeatureclass_management(tempfc.split("/")[0], tempfc.split("/")[1], "POLYLINE", "", "", "", sr) field = arcpy.ListFields(cenfc, cenfld) fielddict = {"SmallInteger": "SHORT", "Integer": "LONG", "Single": "FLOAT", "Double": "DOUBLE", "String": "TEXT", "Date": "DATE", "BLOB": "BLOB"} fieldtype = fielddict.get(field[0].type) if fieldtype == "TEXT": arcpy.AddField_management(tempfc, cenfld, fieldtype, "", "", str(field[0].length)) else: arcpy.AddField_management(tempfc, cenfld, fieldtype, "", "", "", "", "NULLABLE") # Add spider lines print "Adding spider lines..." cursor = arcpy.da.InsertCursor(tempfc, [cenfld, "SHAPE@"]) for line in linelist: cursor.insertRow(line) del cursor # Save spider lines to spider line feature print "Saving spider lines..." arcpy.env.overwriteOutput = True arcpy.CopyFeatures_management(tempfc, spiderfc) arcpy.Delete_management(tempfc) # All done print "All done!"‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Many thanks

Thank you,  Yes I am able to use the template,  but i got only the empty schema, no data.

Check the examples and help here: Create Feature Class—Help | ArcGIS for Desktop

The template feature class is the fourth parameter - the new feature class will contain the fields in the template feature class.

Yes Darren, this what I did in line 36, arcpy.CreateFeatureclass_management(tempfc.split("/")[0], tempfc.split("/")[1], "POLYLINE", "", "", "", sr) but how to include all the fields from the relfc, in_memory then copy them as I did on line 55
