insert() & selection
how can i draw only the scenes that is shown
1. currently, when loadin file multifully with insert() in dwgdirect, it takes a lot of memory in db and reaction time is slow.
i'd like to use 'thread' to enhance the perfomance, and in some ase put in or take out dwg files from the db.
how can i achieve this goal.
2. dwgdirect draws all the scenes even the one hidden behind the screen. how can i draw only the scenes that is shown.
after loading multiple files from the database, can i get the filenames from the scene?
3. i made a selection function.
i'd like to get the features such as name, coordinates, etc., out of selected object.
how can i do that?
