Hi Gertwin, I have done the first test on writing a pythoncad point in to the db structure. It takes 0.25 s for one entity ... Suppose to have a dxf with 100000 entities ...it's around 7 our on my dual core 2.4 GHz machine ... Could you please have a look at my code ..may be I've made some conceptual errors.. Now at each insert I perform a commit ... may be for massive import this slow down the performance .. We can think of something for massive operation... that make the commit at the end of the import and do not write infos into the undo .. Let me know..
