Using arcpy.mapping to extrude point features for converting to 3D features

Hi All,

I am trying to automate a process of converting point centroids, extruding them and then converting them to 3D features.

This is a small section in a much larger process, but is it possible using arcpy.mapping to:

1) add the point centroid file (already have calculated a field called "height") - arcpy.mapping.AddLayer

2) extrude point features - the missing link

3) convert to 3D features - 'Layer 3D to feature class".

Advice appreciated.

Regards,

Craig
