Intersect tool; automatically changes the field names.

[ToyaShannon]

Why does the attribute name fields change after performing an intersect?

[JoeBorgione]

Can you provide an example?  What version ArcGIS are you using?

[ToyaShannon]

I am using 10.3.

Attribute table AFTER intersect:

I'm using 10.0; it adds a few fields but leaves the originals intact.  Sorry, can't comment on 10.3; you may have discovered an undocumented feature, aka bug....

[ToyaShannon]

It's weird. This particular intersection has changed the name of the original fields altogether. Thanks for your time.

Try unslecting 'ALL' from the 'JoinAttributes' field in the 'Interset' tool window. Instead, select 'ONLY_FID'.

Are you sure it is replacing the fields and not just inserting and pushing the original fields to the right?

Let me know what happens.

[ToyaShannon]

Thanks Mitch Muskchamp, but selecting 'ONLY FID', deleted all the data in the attribute table.

[MitchHolley1]

Could you zip the two files you're attempting to run this 'Intersect' process on and post them here?

[ToyaShannon]

Oh how I wish I could; unfortunately this data has privileged information.

Again, are you sure the new fields aren't just added fields?  And they're just pushing over the older fields to the right?
