Often times there is a need to keepout ground fill on one or more layers from under an SMT pad or a microstrip line.

I uploaded to the group's web page a perl script called Object2NetKeepout.pl to do this automatically. It can be found here: http://tech.groups.yahoo.com/group/PantheonUsers/files/

All you have to do is select some primitive objects that represent the area you want to stay clear of. Then run the perl script by either the menu or a newly programmed function key to get the dialog box to open. Specify the layers you want the keepout on, which nets to keepout, and how far away from the selected objects you want the nets to stay. Then execute the dialog box.
