Creating Vias
Vias may be added to your circuit in a number of ways in the project editor. Both the direction and type of via is chosen in the Insert - Via menu. You may also add vias to your circuit by creating Via Technology Layers, then assigning via polygons to the Technology Layer. For more information about Technology Layers, please see Technology Layers.
You may also use buttons in the Insert tool bar to add vias and control the direction in which the via extends.
