Using custom via variant during layer transition

Hi,

I know this is probably obvious but I can't seem to figure it out. Is there a way to use custom via variants during via selection in the wire layer transition mode? I'm trying to figure out a way to change the number of rows/columns of vias when changing layers during the "wire" command. When creating a wire the default via creates only a 1x1 via for the given wire size as shown in the picture (left). I want to specify to use a minimum of 2 vias as shown in the next picture(right). I made a via variant for this but it's not available in the options in the layer transition. Is there an option to do this? Currently after creating the wires I go and change the property of each via stack and add a row.

Thank you,

Eugene

    Hi Eugene,

    Have you tried specifying the Min Num Cuts (as 2) in the Wire Assistant ? I don't think that helps with interactive routing, but it should for 'assisted' routing.

    Best regards,

    Lawrence.

    Awesome! Thank you Lawrence!

    This may have been obvious but I have not seen the wire assistant settings (learned something new) and there is no mention in the documentation for create wire. It works for interactive routing as well, which makes me think that option should also be in that menu.

    Thanks for the tip,

    Eugene
