Defining the Via Types for Use with Your Board in CircuitMaker
The Home | Via Types region accessed from the Layer Stack Manager editor includes commands to add and delete additional via types and to replace the current drill-pairs with pairs created from the actual vias currently used on the board.
Add
Click Add to add an additional via type. This new definition will have a name of <Type> <FirstLayer>:<LastLayer> (e.g., Thru 1:2). You can define the layers that the via spans in the Inspector panel.
The newly added via type will be located alongside any preexisting via types.
Delete
Click Delete to delete the currently selected via type.
From Used
The From Used button is used to replace the current drill pairs with pairs created from the actual vias currently used on the board.
A confirmation dialog will open; click Yes to effect the replacement.
