The Choose Via Sizes dialog

Summary

The Choose Via Sizes dialog is used to custom define Via hole and diameter sizes.

Access

The dialog is accessed by pressing Shift+V while interactively routing (Route » Interactive Routing).

In order to use the dialog to custom define via sizes, ensure the Via Size Mode option under the Interactive Routing Width Sources region of the PCB Editor - Interactive Routing page of the Preferences dialog is set to User Choice

Options/Controls

Select a Via in the left-hand pane of the dialog to view and edit the sizes for that Via. When you select a Via, the right side of the dialog displays information for the selected Via.

  • Diameters - this information is for viewing only in the dialog. It allows you to see whether the Via's diamater is set to Simple (Via hole size and diameter are the same through all layers), Top-Middle-Bottom (different Hole Size and Diameters can be set at Top Layer, Middle Layer and Bottom Layer), or Full Stack (different Hole Size and Diameters can be edited at each layer, including all signal layers and planes).
  • Hole Size - click in the text field to edit the hole size (the inner diameter) of the Via.
  • Diameter - click in the text field to edit the outer diameter of the Via. For Vias set to Top-Middle-Bottom or Full Stack, you will need to individually enter a diameter for each available layer.
