MagicDraw 18.3 Documentation
If you need to open a model of a different format or created with another UML tool, you have to import it to MagicDraw instead of simply opening it. MagicDraw allows importing projects from the following file formats:
Most of the model data from an Enterprise Architect 7.1, 7.5 or 8.0 file.
Enterprise Architect does not export 100% standard UML 2.1 XMI, and this causes some data loss during the import.
UML diagrams from Microsoft Visio using XMI files.
Microsoft Visio 2007 and earlier requires extra add-ons for exporting UML model to XMI files.
