modelspace entities only
modelspace entities only
i got my stuff churning through entities and displaying them just dandy.
then it occurs to me i only want to display entities in modelspace only.
????
how do i search the database for modelspace entities only?
never mind
i figured it out after some sleep...

modelspace is the block "*model_space". another way to get the modelspace ist the function odªdbªdatabase::ªgetªmodelªspaceªid ().

when you like to display modelspace only, do something like that:
oddbdictionaryptr playoutdict = pdb->getlayoutdictionaryid().safeopenobject();
oddbdictionaryiteratorptr piter = playoutdict->newiterator();
bool bmodelspace = false;
while (!piter->done() || bmodelspace == true)
{
oddblayoutptr playout = piter->objectid().safeopenobject();
if (playout->getblocktablerecordid() == pdb->getmodelspaceid())
{
pdb->setcurrentlayout(playout->id());
bmodelspace = false;
}
piter->next();
}
sleep well
