hi all,
actually i have got the dwg height and width. but my requirement is to get the bounding rectangle of the entire entities. is there any function for that or will i have to traverse all the entity, check it and find out the boundary..?
i have used the following way to get the extents of drawings...
is that the right way to get the extents of the drawing..?
odgepoint3d min, max;
oddbextents ext;
cstring str;
oddbblocktablerecordptr pmainblock = theapp.m_pdb->getmodelspaceid().safeopenobject(oddb::kforwrite) ;
ext.addblockext(oddbblocktablerecordptr( database()->getactivelayoutbtrid().safeopenobject()));
if (ext.isvalidextents())
{
min = ext.minpoint();
max = ext.maxpoint();
str.format("%lf : %lf : %lf : %lf", min.x, min.y, max.x, max.y);
messagebox (str);
}

you are on the right way but using getactivelayoutbtrid() you'll get extents of the active layout (model or one of paper spaces - active)
if you need model layout use getmodelspaceid()
