Do not fret! Palette CAD has an automatic backup save function. By default, the software creates a backup save every 20 steps. The file is saved to the same folder as your normal save, but instead of being a .p3d extension, it is .p3b.
To open the file, click “Open existing project”, then select the “Display auto save files” check box.
It is important to note that the Backup file is only a “light” save file to ensure top performance from the program, and therefore it is occasionally possible for materials or objects to be missing when it is loaded. So, while this can save you in a pinch, you should be hitting the standard save button regularly to keep your work safe.
To change the settings of the Automatic backup, go to File --> Program --> settings --> Input/output --> Object Browser:
So, the moral of the story, Save, Save, Save!
