No. Stardraw Design 7.4 does not AutoSave.

You are responsible for saving your work and we recommend that you save regularly; just hit Ctrl+S at appropriate times while you work, or use Ctrl+Shift+S (Save As) to create versioned copies of your important project files.

Stardraw Design 7.4 does include a separate Recovery feature, which is intended for disaster mitigation only — not as a substitute for saving. The Recovery feature creates copies of any open projects when it runs at its scheduled interval and, if the application exits unexpectedly (for example, due to a power failure), the next time you run Stardraw Design 7.4 you will have the option to load the Recovery files. If the program exits normally, however, any Recovery files will be deleted.

Recovery settings can be found under Tools › Personalization › Application Settings and are documented in the Help system.

Recovery should not be confused with AutoSave, nor relied on instead of saving regularly.
