![]() Stops iteration if all input values meet the specified condition of true or false. The Merge Branch tool merges two or more logical branches into a single output. ![]() UtilityĮvaluates whether the specified data exists.Įvaluates if the input data has the specified fields.Ĭhecks whether the input data includes a selection and whether a certain number of records are selected.Įvaluates the input data for the specified coordinate system.Įvaluates whether the input data matches the specified data type.Įvaluates if a feature class is of the specified feature type.Įvaluates if the values in an attribute field match a specified value, expression, or second field.Įvaluates the row count of the input data and checks whether it matches a specified value.Įvaluates whether the inputs have a specified spatial relationship.Įvaluates an input value compared to a single value, a list of values, or a range of values using a defined comparison operator. Logical tools control the flow of processes in a model and enable if-then-else branching logic. In ModelBuilder, if-then-else logic can be added using the set of built-in logical tools or with custom Python functions or script tools. If-then-else logic can be explained as follows: if the condition is true, then perform an action, else perform a different action. If-then-else logic is a concept for performing actions based on different conditions.
