Save, present, and export
Save explicitly to retain all sequence layouts, active selection, Show all, and header placement. Local saves stay in this browser; cloud projects use your existing private account storage. Project type remains immutable.
Presentation and SVG/PNG export use the current display mode. Show all exports the expanded project on one image; individual mode exports one sequence. Very large diagrams may need individual exports. There is no multipage hierarchy export.
Whole-project .acefy.json uses format version 2 and contains the complete source, hierarchy, and layouts. Import through Projects to preserve editable data. C4 version-1 and existing System Design imports remain compatible. Project export remains available even with invalid source.
