How to export your project to a Mindmap
Showing your project as a mindmap without needing to have a mindmapping application
You can export your project file as a mind map using the Mind Map - Freemind option. All you need to view your mind map is a web browser. This is a great way of sending your Merlin Project file mindmap to other users even if they don't have mind mapping software.
