Saving Project Data Automatically
Twin Builder stores recent actions you performed on the active project in an autosave file. Should a workstation crash or other unexpected problem occur, the autosave file can be used to recover project data up to the most recent autosave. The autosave file is stored in the same directory as the project file and is named Project_Name.aedt.auto by default.
Twin Builder saves all data for the project to the autosave file, except solution data. By default, Twin Builder saves project data after every 10 edits. An edit is any action you perform which changes data in the project or the design – including actions associated with project management, model creation, and solution analysis.
Autosave always increments forward; therefore, even when you undo a command, Twin Builder counts it as an edit.
Once the specified number of edits is carried out, a model-only save will occur. This means that Twin Builder does not save solutions data or clear any undo/redo history.
When Twin Builder autosaves, an .auto extension is appended to the original project file name. For example, Project1.aedt will be saved as Project1.aedt.auto.
When you close a project, Twin Builder deletes the autosave file.
To modify the autosave settings, refer to the Project Options section.
