ModelBuilder using iterator as precondition
Was wondering how I can iterate over field values and when all the iteration is done to move onto the group at the end. I've tried setting a precondition within the loop but that just causes the whole ...
How to skip some steps, and continue the running of a model from a later point, bases on a condition?
I am building a Model in ArcGIS Desktop 10.8. At some point in my model, I am dealing with Line feature classes. I turn them into Polygon feature classes, and then I merge them into one feature class. ...
Running Lookup tool in ModelBuilder using field that was joined in previous step
I'm trying to generate a model (ModelBuilder in ArcMap) that calculates the Landslide Susceptibility Index with standardized inputs (Conditioning factors in raster format and dbf's with weights). The ...
Code to return false if two preconditions are false in Modelbuilder
I'm trying to use Calculate Value in Modelbuilder's Arcmap to run a process if one of two booleans preconditions is true. So if both of precondintion are false the process shouldn't run, otherwise it ...
Preconditions not working on second iteration of ModelBuilder?
I'm working on a project where I have to iterate through geodatabases and handle some debug errors if they exist. For this I've created a ModelBuilder model, in ArcGIS 10.7. Essentially, what the ...
How to use preconditions with row counts when some row counts = 0?
I have a model that iterates through a series of neighborhood polygons and clips several different datasets using the iterated neighborhood polygon. I am trying to determine the number of features ...
Nested iterator in model not working?
I am trying to iterate through 2 folders (1 for points, and 1 for polygons) and use the output values as inputs for another submodel that applies IDW, Focal Statistics, and finally a Clip (to a ...
Running process in ModelBuilder before loading shapefiles?
I have a model which I would like to check if shapefiles exist or are up to date and download them if they are not before processing them. I wrote the script to do the checking. In the script, I use ...
Successful iteration as variable
In ArcGIS ModelBuilder, is it possible to create a variable (that can be used as a precondition for following tools) that tells if an iteration has been finished? Example: An iterator buffers all ...
Dissolve doesn't work with empty layers
I have this model: The tool dissolve has this precondition of the Calculate Tool in order not to run with empty layers: However, when it runs with a empty layer it returns the following error: ...
Iterating rasters in ModelBuilder - wildcard does not seem to work?
I've got some problem with the model below. I want to extract rasters from sde geodatabase, use one parameter from Copy Raster, and then export it to specified folder with preserved names as an ...
ArcMap modelbuilder CalculateValue precondition not working
I am using ModelBuilder in ArcMap 10, this is my model: Cell Statistics shall be calculated for only those rasters dating in summer months (April - October), input raster name format is yYYYYmMM, e.g....
How to calculate multiple variables with precondition
I want to do multiple "calculate values" in ModelBuilder. To make it simple let´s take only 2 simple calculations: 1) calculate sine from angle to variable "MySinus" 2) use this value in a second ...
Use value of Field in Calculation in Modelbilder
In Modelbuilder I have set up a model, where in one step I do a "Calculate Field" like "round((!OID!-1- %MyField% /15)/452,1)+1" . For the calculation i use the value of %MyField%, which actually is ...
Setting creation of feature dataset as precondition to iterative process using ArcGIS ModelBuilder?
When using ArcGIS ModelBuilder, how do you set the creation of a feature dataset as a precondition to an iterative process, and not have it re-create the feature dataset each time through? This is ...
