Before exiting solidThinking, you should save your work using the File > Save menu command.
A file selector is brought up allowing you to name the document and save it either in solidThinking file format (.st) or in another supported format.
If the file already has a name, the program will overwrite it. If you don't want to overwrite it, but rather assign a new name, you must instead use the File > Save as menu command.
solidThinking native file format is characterized by the .st extension and includes the geometry at the time you save, plus the following information:
- materials;
- lights;
- camera settings.
You can exit solidThinking by selecting the File > Exit command. If the current document is not saved, the program prompts you on whether you want to save it or not. Options are: Yes, No or Cancel to cancel the command and remove the box.
