I have a question regarding using the Conditional Branch algorithm in the Graphical Model Builder.
I am building a rather complicated model with many branches but not every branch needs to be used every time. So I want to use the Conditional Branch algorithm to check the
"art" column of the attribute table from my input layer and to only run that branch if a given value is present, PX or QX in this particular case.
The model will have at least 15 branches when I am finished but usually only a few will be needed per job.
So, I need to use the Conditional Branch algorithm as a kind of if/else filter where if the value is present it runs the branch elsewise it ignores that branch and moves on to the next one.
How do I set up the Conditional Branch so that it ignores that branch unless the value is present?
(Pic isn't my main model, just an example)
