I want to be able to do auto void with same net via if the copper can not cover all of land area. 
Only possible with static shape as of the moment. I can not find any way to do it on dynamic shape.

    Hi Caasmo,

    So you want your via to go from this: 

    to this:

    Is that right?

    Yeah, You are right! What I was trying to do is for example to minimize the modifications of GND shape when placing to free spaces. 
    I have a rectangular board and then create a dynamic GND shape to speed up the process.

    In your example, the center of the via is not within the shape, so it should get auto-voided. (the via is not connected to the shape)

    In his

    example, the center of the via is within the shape but does not get auto-voided.(the via is connected to the shape)

    I posted this question before and received no solution. We get DFM's for these instances from our fab shops. Let us know if you have a solution please.
