 Last update: 31.07.2026 

**Version: 0.0.0**

## Description

Maps values from a min and max field container, according to a mapping defined in a Property field. The property field contains a list of ids for every entity. The operator then computes the minimum/maximum of all the linked entities in the list. The maximum is computed according to the 'value' label. An output container is generated that contains the value, mode, global\_layer\_in\_stack, local\_layer\_in\_element and solid\_element\_id. Example: - Mapping field {1: {4,5}, 2: {8}} - Max Container with the following fields: -- value {4: 10, 5:20, 8: 30} -- mode {4: 1, 5: 2, 8: 3} -- layer\_index {4: 3, 5: 5, 8: 7} -- layers per element field: {4: 3, 5: 7, 8: 2}Will result in an Max Container with the following fields: -- value {1: 20, 2: 30} -- mode {1: 2, 2: 3} -- global\_layer\_in\_stack {1: 8, 2: 17} -- local\_layer\_in\_element {1: 5, 2: 7} -- solid\_element\_id {1: 5, 2: 8} And similarly for the min container.
