"I have a board with six planes replicated across 3 layers. When I add a via, I need a fast way to redraw the planes so the via is included. Right now I have to select each plane and go through ""shape"", ""select shape"", select the plane that I want to update, right click on the plane select parameters and then apply. It gets to be a real pain having to do this for each plane and hopefully not forget one. Is there a better way?"
Assuming you are using an older version of Allegro, why not delete two of the duplicate planes and z-copy the one plane when you are completely done with the routing?
