how to retrieve data in custom objects
how do i retrieve all the data in a custom object?
i derived a custom class from oddbentity. i could get objects of the class created by readfile. dwginfields gets called. actually i want dxfinfield to get called because i want to get the data like the below. (i dumped the data from a dwg file to a dxf text format)

i used to get those attributes in objectarx like
code:
for (resbuf *prb= acdbentget(objname); prb; prb= prb->rbnext)
{
switch (prb->restype)
{
case 10:
m_p3startpoint.setelements(prb->resval.rpoint[0], prb->resval.rpoint[1], prb->resval.rpoint[2]);
break;
case 11:
m_p3endpoint.setelements(prb->resval.rpoint[0], prb->resval.rpoint[1], prb->resval.rpoint[2]);
break;
case 40:
m_lfradius = prb->resval.rreal;
break;
}
}
how can i access those data 10 (20, 30) and 11 (21, 31) in point3d and 40 in real number?
custom object (entity) data can't be converted between dxf and dwg by dd automaticaly. you need implement both dwginfields() and dxfinfields().
