I am working on a 4-layer board using LAYOUT of GENESYS 2007.08. When placing a viahole that contacts only layers 1 and 2 of the board, GENESYS LAYOUT correctly shows a hole on only layers 1 & 2 but incorrectly places viahole-pads on all four layers of the board. My workaround was to specify a diameter of zero for the automatically-generated viahole pads. I then manually place pads around the viahole on layers 1 & 2 using the LAYOUT pad tool. -anybody know another way to do this?
