purge
do you mean something like the purge command in autocad?
i'm new here so i have no idea how to implement this without acad but i thought i'd just try to clarify.
good luck
if you erase entities with oddbobject::erase() method they stay in memory untill database is destroyed. erased objects are not saved to file. so if the problem is that "the database is too large for saving" you need not do anything.
if the problem is that the large number of erased entities still occupy a lot of memory while you need to continue working with the drawing see developers guide / paging support.
