When saving a model or a group, the SGP Model Editor always asks you if you prefer saving them in your library or in a current project. However, the second possibility is active just when a project is opened at that time.

When you save a model or a group in the library, all your projects will be allowed to use it. However, you must carefully pass all the necessary model and group files to the other applicants whenever you hand the project over.

When you save a model or a group in the project, you do not have to worry about their addition to the handed project. However, you will be able to use them just for the specific project.

The B4 enables you to keep a proper grasp of your models even if you have defined a lot of them. This is because all the model and group files are saved in two layers according to their names.

The first part as far as the first period is considered a symbolical component, while the second part is the real name of the file. (The extension does not count)

Thus you can divide your models into categories that will appear, when you choose the first parts of the names properly, in the left bar of the window Model Viewer displayed similarly to the folders in a directory.
