Issue:

ZWCAD Fails to bind the external reference, error message"Some objects in one or more specified external references cannot be bound." occurs, what's the reason?

Causes:

The external reference contains custom objects, and the default setting does not support the copying of custom objects.

Solution:

Input ZWWCLONEPROXYPOLICY in the command line, press Enter, and change its value to 3, then binding the external reference will be supported.
