Freeplane — The Complete Guide: Free Mind Maps and Work Breakdown Trees for Engineers
Freeplane is open-source software for building mind maps and tree structures. Each node can hold text, notes, links, attachments and attributes, and the map grows without turning into a mess. It is written in Java and runs on Windows, macOS and Linux.

- Maps and trees — adding, folding and moving branches with the keyboard alone.
- Conditional styles — colour or icon by status, owner or attribute value.
- Formulas — summing costs or hours from branches up to the parent node.
- Links and files — pointing to drawings, documents and folders.
- Filtering and search — showing part of the map by a condition.
How engineers use it
Build a work breakdown structure (WBS) before opening scheduling software, break a failure into possible causes in a fault tree, or sketch the structure of a report chapter before writing. Students summarise an entire course as a single tree.
