If you are using the symbol wizard or the Parts utility to
automatically generate symbols for model definitions, and you
want to base the new symbols on a custom graphic standard
(rather than the MicroSim default symbols), then you can
change which underlying symbols either utility uses by setting
up your own set of symbols.

Create a symbol library with the custom symbols.
Be sure to name these symbols by their device type as
shown in Table 5-1; this is how the symbol wizard and the
Parts utility determine which symbol to use for a model
definition.

Note
If you use a custom
symbol set, the symbol wizard
and the Parts utility always
check the custom symbol
library first for a symbol that
matches the model definition.
If none can be found, they use
the MicroSim default symbol
instead.
