VScad3 File Menu

2.1.1 Load.

"File / Load => Session..." : Use this menu selection to select and load a previously-saved ".ses" session file. Session files contain all the geometry (cad model), views (page layout), attributes (colors, fonts, etc.) that existed when the session was saved. 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 / Load => Model..." : This will load a previously-saved ".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. In some cases, loaded geometry may be invisible because it is clipped or outside the view. Select the "Workspace / Region..." menu and click on "Auto Adjust" (and then "Apply") to ensure that all current geometry is visible.

"File / Load => Drawing..." : This will load a previously-saved ".cad" CAD Model file as the drawing background. Any existing drawing background will be deleted. The "File / Load => Model..." function loads geometry into the current view(s). The "File / Load => Drawing..." function loads geometry (such as a page border and title block) onto the page background. Views of the current model are placed on top of the background page.

"File / Load => Symbols..." : This will load a ".sym" file containing symbols. A symbol is a collection of entities that are placed as a unit (usually multiple times) in the model. When a symbol file is loaded, the symbols are not added to the model. They are added to the list of available symbols for individual (manual) placement in the model.

"File / Load => Patterns..." : This will load a ".pat" file containing cross-hatch fill patterns for use by Polygon entities.

"File / Load => Fonts..." : This will load a ".fnt" file containing font definitions for use by Annotation entities.

"File / Load => Colors..." : This will load a ".pal" color palette file containing definitions for individual colors.

"File / Load => Lights..." : This will load a ".lit" file containing illumination lights. When loaded, the new lights will illuminate the model.

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.
