HOW TO GET field value FROM selected features INTO field of a different feature class

AlexGray — Thu, 08 Dec 2011 14:59:07 GMT

Okay, so.. I created this model to:

select by location of one feature class to another.

iterate through the selected features of the second feature class

obtain the value from a field

calculate the field in the selecting feature class with the value from the selected feature class

Problem:

Iterator goes through each selected row to obtain the value

There are 34000 rows selected

A calculation is being done as each row value is found

The process it taking forever

It would be faster to just do a spatial join in ArcMap

Then calculate the field I want the values in

Solution:
I am looking for some solution that would be using Modelbuilder.
Any help would be appreciated.

Alex,

May be I'm misunderstanding the models logic but I have a question? I'm assuming inputs Address2 and Select Features:Address are the same layer (may be a point layer)? You do a query selection on this and use this selection to select the parcels. Then you use an iterator which is grouping by recnum. Is recnum unique within the selection? If so then with each iteration you are writing recnum to the selection in the address layer and this I guessing is overwriting the value again? If this model is allowed to run to completion is the value written into Adress the very last recnum?
