Auto-Router and Via Diameter

autodeskguest

How do I get the auto router to use a specified diameter for the vias?  I

hate using the DRC to specify the annular ring of holes since it then means

that large holes and small vias all have the same minimum annular

ring--which is wrong.

 

I want my vias to have a 0.020" diameter but the auto-router keeps setting

them to auto.

    James,

     

    the Autorouter always takes the "auto diameter" option for vias. It's

    the resulting diameter from minimum drill and restring from the Design

    Rules. There is no other option.

    Hi

     

    Refining Richard's response:

     

    If you have a net class set with drill sizes greater than the minimum

    drill size set in the DRC then the auto-router will use the drill size

    of the net class and calculate the restring size from it.
