Issue:

Using [Ctrl + C] and [Ctrl + V] to copy and paste entities in ZWCAD, why it becomes an OLE object?

Causes:

The system variable [COPYCLIPFORMATS] controls the format of the pasted object, when the value is [1], the format is OLE object (ZWCAD graphics, metafile, bitmap).

Solution:

Enter the command [COPYCLIPFORMATS], and change its value to [193].
