Symbol properties
Every symbol has a number, default reference, default type, and a comment. When editing a symbol, you can configure these in F12 - Document - Symbol.
Number identifies the symbol according to its standard, in the format standard:symbol number (e.g. EN 60617: 04-01-01).
The default reference is the symbol's identifier - for example R for resistor, C for capacitor, T for transistor. References are numbered automatically in drawings.
The default type defines the electrical properties of the symbol (e.g. resistance in Ω, capacity in pF). This becomes the initial type in the diagram, and you can change it anytime. If no type is specified, the reference and type won't appear in the diagram.
Comment - an optional description of the symbol.
Function - the symbol's function is important for the program to work correctly.
Initial values for reference and type
You can set initial values for Reference and Type using the Library Configuration tool. Go to File - Library Configuration.
In the dialog that opens, select the Symbols tab. Choose a symbol group in the left pane, then specify the initial reference and type values for that group's symbols in the right pane.
When you're done, close the window and run View - Reread symbols to apply the changes.
Default reference and type visibility
If a symbol has a default reference and type filled in (either in the symbol editor or library configuration), the reference and type will be visible when you insert the symbol into a drawing.
