Now I'm stuck on how to merge it all back together. You need to place your iterator in its own model with attached downstream processing then that becomes a model in your master model. This means EVERYTHING will run x number of times. ![]() I'm using row iterator to select out each polygon, then use the clip tool to clip the road map, then using the dissolve tool to dissolve all of the roads inside that polygon into one record. Golden rule with model builder is that a model with an iterator will execute as many times as it loops. How do I collect all of those outputs and merge them? Using row iterator the model only spits out one shapefile at a time after running a clip and dissolve on it. Populate the null fields in the polygon shapefile with the values from the selected points features (same as the value from unique list). Select polygon features by location using previously selected points that are contained within the polygons. If I clip the road map and then dissolve everything is fine, the issue is the merge. Select the points features by attribute based on name in the unique list. This is what I tried but I get the following error: Cannot use object of type stdClass as array Controller sn. I need for each feature class a field calculated based on the individual polygon locations within the area of the selected row. I know the easiest solution would be to dissolve the roads layer before hand and then clip using the polygons but I'm working on a continental scale and my computer keeps running out of memory for that. I am trying to simply iterate though a result set in laravel on the controller side. The sub model has a iterate feature class instance and the main model has an iterate row selection. The three iterators correspond to the same objective: select the input. There are three types of iterators: Iterate the selection entity. a processing to various layers, you use the layer iterators. The goal is to have a shapefile with each polygon as one record that contains the total roads within that polygon. In this case, it is similar : when you want apply. if field1, go back to the previous row and assign the field with a new value based on an equation, then stop. I need to take each polygon and use it to clip the road map, dissolve all of the road records into one, and then merge the polygons into one shapefile. I would like to use 'iterate row selection in ModelBuilder' and for each row, I want to use the field calculator's code block to create a conditional statement that goes: If field0 then go to the next row. ![]() I have a layer with several polygons and a road map.
