xrecord hard reference pointer

[Martin (archive)]

In autolisp how I can make xrecord in a dictionary that has a hard reference pointer to a perment entity like layer 0 so he will not be erased when purging or wblocking? Thanks you.

Thank you. one thing I found is that for any child xrecord to persist its parent dictionary need have have the 280 group code set to 1 ( it is defualts to 0 ). of course, this is in the dxf references. thanks again Herman.

A Google search of this NG turned up a 5 article thread started on 1/17/02 by Jim Fisher.

There are two replies by John Uhden which delineate two methods for attaching an extension dictionary to layer 0.

One method uses Active X, the other does not.
