The INSERT entity is just one explicit use case, but there are also many indirect block references and the customizability of DXF allows you to store block names and handles in many places. There are some rules for storing names and handles and this module checks all of these known rules, but there is no guarantee that everyone follows these rules. Therefore, it is still possible to destroy a DXF document by deleting an absolutely necessary block definition. .. versionadded:: 1.3.5 r)rsetrsis_alive is_any_layoutr7r)add)r ref_counterunreferenced_blocksrvcounts rrrsk&(,K$'E~~!4!4 ##EJJ/ A:  # #EJJ /  rN)rdzIterable[DXFEntity]rKrr8r)rerr8r\)rar r8r\)rz 'Drawing'r8r\)rr r8zset[str]) __future__rtypingrrrr collectionsrezdxf.lldxf.typesr ezdxf.protocolsr ezdxf.documentr ezdxf.lldxf.tagsr r]rr__all__rrrEr^r`rJrrArrrsx#>>+-&%5 W'T7*7*t)%)%X!*> 4D4r
