InfraWorks supports the use of custom coordinate systems (CS). Either the complete model of single data sources can be created/loaded with custom CS.
But if a model is opened on a computer that doesn't have the custom coordinate system available, an error appears.
The request is to save custom CS definition in the model database.
Similar to a DWG in Civil 3D or Map 3D the user should be prompted to import the custom CS when he opens an InfraWorks model with custom CS.
