dwg without layout extension information

dwg without layout extension information
hi,
trying to getting the bounding box in wcs of a dwg i found some files without information about layout extension.
i tried getting layout extension information using two methods:
1)
min = playout->getlimmin();
max = playout->getlimmax();
2)
playout->getgeomextents( layext );
and often i get min & max = (0.0, 0.0) and the same for layext.
dwg files can not contain this information?
is there a way to force dwgdirect to calculate them?

extents information saved in file may be incorrect. to force extents calculation you can use:
use getgeomextents() of layout block.

this function returns extensions in model coordinates, is it right?
then to have them in wcs do i need to use view matrix?

getgeomextents() for layout block returns extents in world coordinate system (wcs).
