Issue: 

When opening a ZWCAD drawing with AutoCAD, a prompt appears indicating that AutoCAD did not save the file. Does this mean ZWCAD's format is different from AutoCAD, and will it affect my work?

Solution:

The pop-up of this window does not affect the content of the drawing. Select the option in the lower-left corner of the picture below, then open the DWG drawing; this window prompt will not appear.
