各位大虾帮帮忙,谢谢.

scantocad,或vp,不过效果很难恭维。。呵呵

如果只是参考,用插入文件就可以了啊,如果想要图中的线,最好还是自己画吧.

If you don’t want to change .tif you can: insert---raster image... and select .tif file whatever you want.
If you want to change you should insert than trace it by yourself.

or use special software to conver it

网上有扫描文件转换为cad文件。试试吧

谢谢,各位朋友
