Hello Everyone,

   I need to run arcpy.FeatureVerticesToPoints_management() method in ArcGIS 10.1 Desktop Standard, but it has License just for ArcGIS Desktop Advanced. Can anyone suggest me any other alternative to get the point layer of the vertices like I get in  FeatureVerticesToPoints_management() method..

Thanks and Regards..

Find below the code that I used to recreate the Feature Vertices To Points tool for Basic licenses (sorry for the Spanish interface):

FeatureClassToNumPyArray with the explode_to_points option set to True

http://desktop.arcgis.com/en/arcmap/latest/analyze/arcpy-data-access/featureclasstonumpyarray.htm

Then Numpyarraytofeatureclass to get the exploded geometry back to points.

Or some searchcursor approach doing effectively what the above does

Sir,As per your approach,The coordinates I am getting are of the center of the lines, Is there any way to get the vertices of the line i.e. the start and the end points of the line.

You can create two fields for start point and two fields for end points of line (XStart / YStart / XEnd / YEnd), and use 'Calculate Geometry' to get this coordinates.

You didn't specify the explode_to_points=True (check http://desktop.arcgis.com/en/arcmap/latest/analyze/arcpy-data-access/featureclasstonumpyarray.htm

that is why you are getting the centroid only

If you need only the Coordinates of points and working with Enterprise Geodatabase, you can read the coordinates with a Query layer or using the RDBMS tools with a function like ST_ASTEXT and getting all of the coordinates.

I'm getting the same error with this code. It worked for me in ArcMap but not when I run it in Pro.

Could it be differences between Python 2 and 3? I'm not familiar enough with syntax differences between the two that might be tripping me up in Pro. Any ideas?
