It is used to archive the project and reduce its size. Projects saved with the "Save with Compress" command are compressed, so their size is smaller than the projects saved with the "Save" command (.ide10).
To save the project by compressing:
Click the Project / Save by Compress line in the classic menu and the Save by Compress icon from the menu that opens when you click the ideCAD logo on the top left of the screen in the ribbon menu . The Save Project window will be displayed.
From here, switch to the folder you want.
Type a name for the project file you want to save by compressing it on the file name line.
Click the Save button.
Compressed project will be saved as .cde extension.
When you save your project by compression, it takes less space on your disk and saves you time transferring to another disk. It is convenient when you want to send it by e-mail or upload it online. The size of your file saved in the .cde format varies depending on the number of elements and the content of your two-dimensional drawings you have stored in your project.
The difference between Save by Compress and Save Project is shown in the sample project shown in the screenshot below .
