[GIS] way to convert 3D polylines to 3D points in ArcGIS

Question

I need to convert a huge number of very dense (densified to 1m) 3D polylines to 3D points.
I need each vertex along the line and no duplicates (two of the same XYZ coordinates) if possible. Is there a tool for that? Each feature class to be converted yields about 1 to 2 million points.
I did write my own add-on for this and although I am using the insert cursor (as oppose to iFeature:Store) it's quite slow so I am hoping there is a better way.

Answer 1

Have you tried ET GeoWizards perhaps? I know it can do 2D polylines to points in the free version, but I'm not sure about 3D.
