How to Add Point Number/Codes To Lists Without Them.
Some point list formats do not have point numbers (or point codes) in them, the XYZ format for example. I'll show you how to use Pointor to add a column of points to the 3 columns of XYZ data, though of course the same technique will work with other numberless/codeless point list files.

Step 2: Use the point list icon to confirm that there are no codes in the list, just coordinates.
Step 3: Use the Edit | Copy Pointlist to Clipboard menu utem:
