load dwg file from buffer
forgive me in advance, i'm new to cad and the libraries, but a quick question...
i am trying to implement the ability to load an oddbdatabase object from a memory stream, and see the basic way to do it (i.e. implement a custom odstreambuf, override the appropriate readfile () in my host app services object, etc.), but am getting lost in the details.
has anyone successfully implemented this functionality that can share it? it seems that this would be something commonly done, but i haven't seen any sample implementations and discussion on the topic appears limited.
thanks,
chris
