★Why the command line prompt "Ignore duplicate definition of block xxx" when copying and pasting in ZWCAD?

Issue:

When users copy and paste, the command line prompts "Ignore duplicate definition of block XXX", "XXX" represents the block name. Why it appears? Does it mean that there is a problem with the software or the drawing?

Causes:

This is a very normal prompt and has nothing to do with whether the drawing or software is damaged.

This prompt appears because the block object being copied has the same name as the existing block object in the drawing, and when pasting, it will prompt to ignore the duplicate definition of the block with the same name. The block deferred from the drawing will not be updated to the content of the block being copied.

If the object has changed after a successful copy and paste between different drawings, users need to pay attention to these block names that ignore duplicate definitions and check whether the graphics of the block with the same name are the same within the two drawings.
