This rule checks to ensure that the used via types match the currently defined via types. The used via types are determined from the vias and pads found in the board. The permissible via types are defined on the Via Types tab of the Layer Stack Manager.

All design rules are created and managed within the PCB Rules and Constraints Editor dialog. For a high-level view of working with the design rules system, see Defining, Scoping & Managing PCB Design Rules.
