thank for the quick response ... i have to copy a hatch entity within the same database. thanks in advance ..
thanks a lot sergey . i used clone function and got the result. thank u again
clone() will produce exact copy of hatch entity which can be appended to a block in the same database but not to another database because it references layer, linetype etc. from the first database.
also note that if the hatch is associative its boundaries will be associated with the same entities as boundaries of original hatch.
in general using clone() for all entities is not safe. for example cloned oddbpolyfacemesh will reference the same vertices and faces as the original one. to clone such complex objects which own subobjects within the same database oddbdatabase::deepcloneobjects() should be used.
for cloning to another database oddbdatabase::wblockcloneobjects() should be used. it will take about references to linetypes, layers etc.
