| InfoWorks CS element ID |
ID used to identify the triangles that have been aggregated into larger elements in order to meet the minimum element area of the triangle's 2D Zone or mesh zone. An InfoWorks CS element ID of zero indicates that the triangle has not been aggregated. A non zero value indicates that the triangle has been aggregated; the other triangles that it is aggregated with will be given the same InfoWorks CS element ID. Only generated for networks containing meshes that have been imported from InfoWorks CS or SD. Note: The import of InfoWorks CS/SD data is deprecated from version 2023.1. However, this result will still be available for data imported using an earlier version of the software. If a network contains meshes that were created in InfoWorks ICM as well as meshes created in InfoWorks CS or SD, then elements in those meshes created in InfoWorks ICM will be given a blank InfoWorks CS Element ID, regardless of the aggregation. If there are no InfoWorks CS or SD meshes in the network, then this result will not be generated at all. Aggregation of meshes created in InfoWorks ICM can instead be viewed using the control settings on the Elements tab of the Geoplan Properties dialog. |
