When creating a new master database, first decide if this will be a Standalone database (saved to the local machine) or a Workgroup database (saved to a shared location like a network drive).
If opening an existing database, creating a new Standalone database, or updating a database from an old version, please open the ICM Help and search for the ‘Master database’ topic to find instructions there for doing all of the above.
If you are creating a new Workgroup Database for the first time, please follow steps 1-6 in the following Knowledgebase article:
Now that a master database is open, data can be imported from a transportable database (.icmt file) or networks and event data from scratch. For further instruction and to get more familiar with the tools in ICM, check out the InfoWorks ICM tutorial.
