How to select a DWG object by its internal ID, its "handle"?

Each drawing object in a DWG file can be identified by its unique ID, a hexadecimal code which does not change through the DWG editing history. Any object (entity) is unambiguously identified by this hexadecimal number code.

If you need to find or select an object by this code, e.g. coming from an error message, you can use the LISP function (handent).

Then you can e.g. delete the complaining object with the command:

(entdel(handent "36A41"))

typed on the command line (replace the sample code 36A41 with your specific hexadecimal handle - the index, listed in the AutoCAD warning message).

To temporarily highlight the object before deleting, you can also use:

(redraw(handent "36A41")3)

To zoom to a specific object - if it is a visible drawing geometry object, use:

_ZOOM _O (handent "36A41") [Enter] [Enter]

or:

(command "_ZOOM" "_O" (handent "36A41") "")
