Often several libraries will contain parameters with the same names, and the diagram needs a way to distinguish between such parameters. SynaptiCAD uses library specifications to make the distinction. In this tutorial the 3ac and ac libraries contain parameters with the same names, so we will use library specifications when we reference these parameter names. If no specification is used when referencing a parameter, the program will use the values of the parameter in the first library that it finds a definition.

Library specification can be remove by selecting them and using the left arrow. You can experiment with this, but make sure the ac and 3ac specifications are assigned before moving on to the next section.
