VScad3 File Menu

2.1.2 Save.

"File / Save => Session..." : Use this menu selection to save a ".ses" session file. Session files will contain all the current geometry (cad model), views (page layout), and attributes (colors, fonts, etc.). A library of special session files could be created - one for each different type of design task to be performed in VScad3. When a session is loaded, all existing entities, attributes, and views are deleted.

"File / Save => Model..." : This will save a ".cad" CAD Model file. Model files contain CAD geometry (annotations, polylines, surfaces, etc.). Model files do not contain attributes (fonts, colors, lighting, etc.). When a Model is loaded, it is merged with any existing model entities. This can also be used to save a ".cad" file for later loading as the drawing background.

"File / Save => Symbols..." : This will save all current symbols to a ".sym" file. A symbol is a collection of entities that are placed as a unit (usually multiple times) in the model.

"File / Save => Patterns..." : This will save all currently-defined crosshatch fill patterns to a ".pat" file.

"File / Save => Fonts..." : This will save all current font definitions to a ".fnt" file.

"File / Save => Lights..." : This will save all current illumination lights to a ".lit" file.

All of the above file formats (".ses", ".cad", "sym", "pat", "fnt", ".pal", and "lit") are a proprietary binary format native to VScad3.

Note that the CAD model, drawing background, symbols, patterns, fonts, colors, lights, and view layout are all saved in session (".ses") files.
