Iterating both inputs for a tool in Modelbuilder

RebeccaFuda

I have 2 folders, one with 3 shapefiles and one with 11.  I want to find the intersection for all possible combinations of the shapefiles in each folder, for a total of 33 resulting intersection shapefiles.  I have tried creating 2 sub-models that iterate through the folders, and used the output of each submodel as the inputs for the Intersect tool.  However, the model results in only one intersection shapefile.  How do I get the intersect tool to use all combinations of the shapefiles?

Test_sub2 submodel                                                                                    Test_sub1 submodel

Sorry Rebecca, been busy teaching, hopefully this will help you or someone else.

Here's the help on nesting models

Here's an example model that does nested loops:
