converting autocad file into corel draw file without any breaking of lines in 1:1 scale

Hi everyone,

Please help me out in this, i am new to coral draw, and it would be really helpful in my work if i get this problem sorted out, I need to export the autocad file to corel draw file with the same scale . I have tried doing it many times but every time there are breaking of lines happening which is the real problem and then it takes me hours to again draw it on coral. i need to give my drawing for the cnc cutitng and the factory guys need it to be in the coral draw format. but i am unable to do it without any broken lines. Please suggest any solution for this. Thank you.
