XY to Line attribute table is all

GabrielMarcus1 — Thu, 16 Aug 2018 01:23:40 GMT

I've got two point features that I am comparing. Both represent physical structures.

The following was my workflow:

1) reprojected features to WGS 84 (4326)

2) I added fields for X and Y values and calculated geometry appropriately

3) joined the first table to the the second

4) Ran XY To Line, and included and ID that was the structure building number

Line Type: Geodesic

ID: buildingID

SpatialRef: GCS_WGS_1984

Results:

XY to Line created the lines, but ALL attributes are <NULL> and the ID field didn't appear.

There were NO errors.

Questions:

Why are the attributes <NULL>?

Where's my ID field?

make the join permanent by saving to a new featureclass... I suspect the join is dumped during output creation

That worked. It's too bad that step doesn't appear in the documentation.

Glad it worked out...

I have just gotten into the habit of making joins permanent every time... you can always delete what you don't want after you are done.

When running the XY to Line arcpy in a Python Notebook in ArcGIS Pro version 3.5.4, the X,Y attributes are NULL with a join table when the "Preserve Attributes" option is unchecked. (IMHO, this is a bug).

If I check the "Preserved Attributes" option, all the attributes are non-NULL including my X,Y attributes.

Or, if I remove the join and run the XY to Line tool with "Preserve Attributes" option unchecked, the X, Y attributes are non-NULL.
