Hi Jason, Your code is returning the correct results.  Take a look at the 'datasetName' property explanation here. Returns the name of the layer's dataset the way it appears in the workspace, not in the TOC. The 'name' property differs: Provides the ability to set or get the name of a layer the way it would appear in the ArcMap table of contents. So, if you were to change the name of the layer in the table of contents, you can still find the original feature class/shapefile name by using the 'datasetName' property. ... View more

Hi Tony, Here is an example on how to do this: import arcpy from arcpy import env env.workspace = r"C:\temp\python\test.gdb" env.overwriteOutput = 1  input = arcpy.GetParameterAsText(0)  # Create empty Point and Array objects point = arcpy.Point() array = arcpy.Array()  # A list that will hold each the Polyline object featureList = []  rows = arcpy.SearchCursor(input) for row in rows:     geom = row.Shape     point.X = geom.centroid.X     point.Y = geom.centroid.Y     # Add each point to the array     array.add(point)      # Create the polyline polyline = arcpy.Polyline(array) # Clear the array for future use array.removeAll() featureList.append(polyline)  del row, rows  # Copy the polyline to file geodatabase to create a Shape_Length field arcpy.CopyFeatures_management(featureList, "line_test") rows = arcpy.SearchCursor("line_test") for row in rows:     # Create a variable to store the length     length = row.Shape_Length     arcpy.AddMessage(length) del row, rows  # Convert the line's end point to a point arcpy.FeatureVerticesToPoints_management("line_test", "point_test", "END") # Add a field to store the length from the point1 to point2 arcpy.AddField_management("point_test", "Length", "DOUBLE")  rows = arcpy.UpdateCursor("point_test") for row in rows:     row.Length = length     rows.updateRow(row)  del row, rows  arcpy.Delete_management("line_test") Once the script is created, you can add it to a toolbox.  After it's added, right-click on the script > Properties > Parameters tab.  Create a parameter and set it to Feature Set for the Data Type.  Within the Parameter Properties, import a feature class or shapefile for the schema.  You can then double click on the script, enter two points on the map and then run the tool. ...

Hi Martin, In ArcMap, go to the Geoprocessing menu > Geoprocessing Options.  Under Script Tool Editor/Debugger set the Editor to the IDLE or PYTHONWIN executable.  Ex: C:\Python27\ArcGIS10.1\Lib\site-packages\pythonwin\Pythonwin.exe ... View more
