Issue:

When objects in the drawing are saved separately by [WBLOCK] command, the corresponding drawing file cannot be created normally, why?

Causes:

There are proxy objects or proxy entities in the drawing. Using [WBLOCK] command is equivalent to making a copy of the drawing.

The system variable [ZWWCLONEPROXYPOLICY] controls whether the proxy object or proxy entity can be copied. The default value is [0], we need to change the value to enable it.

Solution:

Type [ZWWCLONEPROXYPOLICY] in the command line and change the value to [3].
