Ray Now I understand a little better. You could this. I use this trick to keep traces out of certain areas. Place a matrix of 1 mil lines on the bottom and make them KEEP OUT lines. Make the squares in the matrix large enough so the router can pop vias in. The matrix will prevent routes. Set the via grid to 1. Vias will be allowed routes wont
To keep vias out of an area, use an used layer ( I use layer 30) Set layer 30 to no route . Place fills on layer 30 and call make them keep out fills Mike -----Original Message----- From: Ray Mitchell [mailto:[EMAIL PROTECTED] Sent: Thursday, April 08, 2004 11:27 AM To: [EMAIL PROTECTED] Subject: [PEDA] Creating selective keepouts I'm using Protel 99SE SP6. I have components on the top and bottom of my board. In one area of the bottom I would like the autorouter to be allowed to place both vias and traces as needed. In another area of the bottom, however, I would like it to be able to place vias, as needed for routing on other layers, but I don't want it to be able to place any traces. I've tried specifying NOT USED in the design rules for the bottom layer but when I do that it will not route anything anywhere. Any thoughts on this?
