Importing from CSV files
Networks data can be imported from CSV filesComma Separated Variable file format is a standard file format that can be imported and exported by many software packages. Many types of data can be imported and exported using csv format by InfoWorks.. Existing network objects can be updated or deleted and new objects can be added.
The files have to be in an appropriate format and may need specific filenames. Further details on format requirements can be found in CSV file formats.
Full details about how to update networks can be found in the Updating Networks topic.
