[GIS] Multiple input tables for Add Field in ModelBuilder

Question

My model requires field1 to be added to fc1 and fc2, and then calculated according to a Python expression calc1. field2 is then added to fc2, and calculated using calc1. How do I add the multiple feature classes as the input to Add Field and Calculate Field? I have tried creating an input table variable as a list of values, and while it accepts fc1 and fc2 when I type it in, the model does not run ("dataset does not exist").

edit I'm adding these fields so that I can join the tables on a common pre-existing field and populate fc2.field1 with the values from fc1.field1.

Answer 1

Have you tried to use Add Field twice? First for fc1 and then another block for fc2. Add Field tool accepts only single table/feature class as input.

It will look similar to:

If you have many feature classes and want to add field to each of them then you can use iterators in ModelBuilder (take a look at "Iterate Datasets" section) or convert to python script and use loops if you are convenient with python.
