My model selects a feature class within a user specified file geodatabase, based on the output of an IF statement which checks the user specified string value e.g. If the user specifies a file gdb
InputGDB and a string
A, the if statement checks the string and returns true if the string is A. it then chooses the appropriate feature class
InputGDB and continues processing. The same thing happens if the user enters B, i.e. feature class
FC_B would be chosen.
The same processes happen on the feature class, regardless of whether A or B is chosen. My problem is there is a third feature class, also sourced from the same gdb (let's call it
FC_Common), whose processes always run regardless of what is happening with A/B. After some initial processing,
FC_common must interact with A/B via a series of Intersect, Joins, selections etc. How do I set the model up so that I don’t have to duplicate the entire branch of processes for each option?
I've read a bit about the Merge Branch tool, and I think it's what I want, but I'm not entirely sure how to use it. I've attached an image of the model to show where I am having a problem.
