Library Palette

Symbols and parametric parts are groups of objects available for repeated use. While groups and blocks are internal to a drawing, symbols and parts are external files. The Symbols palette is used to display and insert symbols found in the various symbol libraries - both those included with TurboCAD installation and those you create yourself. You can also use the palette to save symbols.
