Topic: how can i remove all dictionaries at once

[andrew_nao]

if i have more than 1 dictionary in a dwg, is there a simple way to remove them all in 1 shot?

[dgorsman]

Depends where they are located (NOD or object extension dictionary).  Aside from iterating a list with (dictremove ...) or (vla-Delete...), there aren't many options.  If there is a host dictionary which holds the target dictionaries you could delete that instead.

[andrew_nao]

well right now i have it working like this with a repeat call

(dictremove (namedobjdict) (strcat "DWGPROPS"item))
i cant seem to find a vla-delete function in the help files. can you provide the full function name

[dgorsman]

(vla-Delete ...), as the name implies, is VLISP which deletes a specific member of a collection.  Substantially the same as (dictremove ...).  Check the Delete method from the COM/ActiveX help.

You don't want to blindly delete all dictionaries from the NOD.  That would be BAD.   :pissed:  Iterating and removing by specific names should be sufficient.

Not quite - since dictremove does not actually delete the dictionary entry, but only removes it from the dictionary - to delete it, one must use entdel (there are of course exceptions to this behaviour where the groups & mlinestyles dictionaries are concerned).

Agreed

Actually if you reopen a dwg after using (dictremove) the dictionary will have been erased. In that sense (dictremove) is very similar to (entdel).
