如何在allegro中删除有过孔或布线的层时不影响其他层

1.输出specctra的dsn文件
allegro->file->export->router->demo.dsn->run
2.产生session文件
specctra(pcb router)->file->write->session->demo.ses->ok
3.删除某一层中的布线和过孔
delete(ctrl+D)->..
4.删除allegro中的板层
setup->cross section->鼠标右键->delete
5.导入session文件
allegro->file->import->router->demo.ses->run

也可先将通过该层的过孔先替换成顶层焊盘,删除该层以后再替换回来
