Excluding Specific Feature classes from ModelBuilder iteration? [duplicate]

Question

This question already has an answer here:

Using Python script as precondition in ArcGIS ModelBuilder? (1 answer)

Closed 8 years ago.

I am creating a model the will iterate through the feature classes in the dataset.

It will select attributes from each feature class, the only issue is, two of the feature classes will cause a break in the process due to being void of the attribute.

Is there a way to exclude the two said feature classes from the iteration?

• PolyGeo: Take a look at the answer to gis.stackexchange.com/questions/112510/… which indicates how to employ if-then logic in ModelBuilder.
• Hornbydd: If you are using a FeatureClass iterator you can use the wildcard parameter to filter out the problematic FeatureClasses if they are name differently.

Answer 1

You could either:

1. use the answer to Using Python script as precondition in ArcGIS ModelBuilder? to employ if-then logic in ModelBuilder; or
2. do as commented by @Hornbydd:

If you are using a FeatureClass iterator you can use the wildcard parameter to filter out the problematic FeatureClasses if they are name differently.
