That's very kind of you.
I must say that the base point problem is already solved with the help of a
(acet-geom-ss-extents sset t)
But I also have to programm some explosions and would be interested.
Do you explode in a model where stand other entities or do you need to export the entire database of the drawing ?
I myself must export a selection set from a general drawing containing other entities.
On the other hand, I must also export as 2004 DWG but would like to export 2000. What a mess, it becomes necessary to open, saveas and close. Therefore, I must deal with multiple SDI-MDI configurations at my office....
If I don't succed, I'll post here
