Hi Barry,

Create or verify this directory exists on your PC:
'c:\temp'

Here is a simple node to record the XYZ values of points.

Save this file as '_PointDetails.js' in the ext file of the node editor.

Start the node editor and load the PointDetails node that was just registered.

Attach a node with a point array output.

Run the node. (No output node required.)

Exit the node editor and exit MoI3d.

Look in the directory for the file 'c:\temp\datapop.txt'. It should be populated with the points detail.
