I have a model in model builder where I add 2 fields, "field 1" and "field 2". For each field I calculate their values using the calculate field tools. Afterwards I add a third called "Field 3" of which the calculation is based on the calculations done in field 1 and field 2.
My questions is if it possible to add the third field directly from my feature class without first calculating field 1 and field 2. If I would calculate field 3 as shown in my picture below, I cannot refer to field 1 and field 2; not even if I use preconditions (without first running the first part of the model until adding field 3).
I realize that this would be possible if I add field 1, calculate field 1, add field 2, calculate field 2, add field 3, and then calculate field 3. In this case 'field 1'and 'field 2' will be shown in my field 3 calculation tool. The problem is that the model visually becomes a very long model that lacks overview (as I need need to do this for more fields before I calculate the last field).
Is there a way in ArcGIS Model Builder to calculate a field based on two other fields without that field 3 is directly linked to the two fields?
