Each type of component has a symbol which is used to represent it on the isometric drawings. A set of default symbols for a wide range of components is supplied with ISODRAFT. The symbols supplied in the standard library are shown in the chapter Symbol Keys, of the ISODRAFT Reference Manual. The user can query the SKEYs in the symbol library index, but the user cannot query symbol attributes and shape definitions.

The user can create new symbols in DRAW or other 2D drawing packages. For the forms and menus used to create the symbols in DRAW, refer to DRAW Administrator Guide. The commands to create symbols are described in the DRAW Reference Manual.
