如果将原理图导入PCB后发现封装或者网络飞线连接有错误，不用在PCB进行修改或者删除错误的元件封装，直接回到原理图修改错误后，再次导入设计即可。
在一个PCB的FreeDocument中，可以直接导入其原理图网络和封装。
I still have a dream. It is a dream deeply rooted in the American dream.I have a dream that one day this nation will rise up, live up to the true meaning of its creed: “We hold these truths to be 1; that all men are created equal.”I have a dream that one day on the red hills of Georgia the sons of former slaves and the sons of former slave-owners will be able to sit down together at the table of brotherhood.I have a dream that one day even the state of Mississippi, a state sweltering with the heat of 2, sweltering with the heat of 3, will be transformed into an oasis of freedom and justice.I have a dream that my four children will one day live in a nation where they will not be judged by the color if their skin but by the content of their character.I have a dream today.I have a dream that one day down in Alabama with its governor having his lips dripping with the words of 4 and nullification, one day right down in Alabama little black boys and black girls will be able to join hands with little white boys and white girls as sisters and brothers.I have a dream today.I have a dream that one day every valley shall be 5, every hill and mountain shall be made low, the rough places will be made plain, and the crooked places will be made straight, and the glory of the Lord shall be revealed, and all flesh shall see it together.This is our hope. This is the faith that I go back to the South with. With this faith we will be able to hew out of the mountain of despair a stone of hope. With this faith we will be able to transform the jangling discords of our nation into a beautiful symphony of 6. With this faith we will be able to work together, to pray together, to struggle together, to go to jail together, to stand up for freedom together, knowing that we will be free one day.This will be the day when all of God’s children will be able to sing with new meaning.My country, ’ tis of thee,Sweet land of liberty,Of thee I sing:Land where my fathers died,Land of the pilgrims’ pride,From every mountainsideLet freedom ring.
