But i need an user opinion:
Alternate via drill value does not work as default value does.
Alternate via drill value is a value that is set for one via, an differents vias can have different drill values.
So Alternate via drill value can be changed to have different drill values, and dialog box shows the last entered value.
(unlike the default value: it is not stored in vias, and if this value changes, all vias set with default value have their drill value changed as
well)
So Alternate via drill could be a bad name if an used can think it is a parameter that works like the default does.
(changing Alternate via drill changes also all drill values set to alt value.)
