I'm sorry to tell you that Tianzheng's drawings are not Tianzheng's drawings after the education edition is cancelled, even cad drawings are not, and your marks should not be gone. According to thenray's practice, there should be marked drawings, but it is not the marking style of Tianzheng, or even the marking style of cad. At this time, you can only try to convert the old drawings into new drawings, that is, Tianzheng's old drawings conversion. ............

Finally, all the drawings can only be completed in the middle of the day, and then they can be printed in the education edition. All the modifications are in the education drawing.
