Replacing Circuitry

The Change... command of the Edit menu removes the currently highlighted node or arc and replaces it with a new one of a different type. A dialog is presented in which the possible replacements are shown.

Figure 6.4

When replacing a node, the existing arcs must be able to reconnect properly to the new node. However, the sizes of the two nodes can be different, and the layout will be adjusted.

Some Schematic nodes use parameters to further describe them. For example, a Schematic Electrolytic Capacitor is really just a Capacitor with the Electrolytic parameter on it. When you change a node into one of these from the Schematic technology, no parameter is set. However, you can use the Get Info command of the Info menu to set the parameter. Besides Capacitors, parameter can be found on Diodes, Transistors, Sources, and Two-Ports (actually four-connection functions).

When you are replacing arcs, the two nodes must be able to accept the new type of arc. It may help to use the Universal arc and the Universal-Pin (from the Generic technology) as a place holder for complex node and arc replacement because they can connect to anything.

Besides replacing the currently highlighted node or arc, it is also possible to specify replacement of many other similar objects. The "Change all in this facet" button requests that all others in the current facet that are of the same type as the highlighted object will also be replaced. The "Change all in this library" button does the replacement everywhere in the current library.
