how to keep the correct visibility after acis convertion
how to keep the correct visibility after acis convertion
hello,
i've got a problem with the function "pent->decomposeforsave(oddb::vac12, replaceid, exchangexdata);" which is used to convert acis elements into polyfacemesh.
if i do this code:
code:
oddbdatabase* pdb = getdocument()->m_pdb;
// open the block table
oddbblocktableptr pblocks = pdb->getblocktableid().safeopenobject();
oddbsymboltableiteratorptr pblkiter = pblocks->newiterator();
// for each block in the block table
for (pblkiter->start(); ! pblkiter->done(); pblkiter->step())
{
// open the block
oddbblocktablerecordptr pblock = pblkiter->getrecordid().safeopenobject();
// get an entity iterator
oddbobjectiteratorptr pentiter = pblock->newiterator();
while(!pentiter->done())
{
oddb::visibility vis = oddb::kvisible;
oddbentityptr pent = pentiter->entity(oddb::kforwrite);
pentiter->step();
if (!pent.isnull()
&& (pent->iskindof(oddbregion::desc())
|| pent->iskindof(oddbbody::desc())
|| pent->iskindof(oddb3dsolid::desc())))
{
bool exchangexdata;
oddbobjectid replaceid;
vis = pent->visibility();
oda_trace1("old visibility: %i\n",vis);
oddbobjectptr pnewobj = pent->decomposeforsave(oddb::vac12, replaceid, exchangexdata);
if (!pnewobj.isnull())
{
pent->handoverto(pnewobj);
vis = pent->visibility();
oda_trace1("new visibility: %i\n",vis);
}
}
}
}i can see with the print that the visibility is the same after the decomposition but if i check all my entities after this main loop i've lost the correct visiblility (if the entity was invisible (code 60 == 1))
what can i do to solve this problem? did i need to do something special after the "handoverto"?
thanks in advance
hello,
mfcapp has acis conversion right click local menu. it makes requested conversion. could you please attach a small sample file, which will show a problem in mfcapp?
also oddbentity::setpropertiesfrom can be helpful.
there is a small exemple with the case outside a block and in block.
in the odamfcapp, the function "acisconversion" don't convert acis elements in blocks. my problem comes from dynamic blocs but it can also append that acis elements are invisible outside a bloc.

hello,
this is new version of the acisconversion
code:
void cdwgview:neditacisconversion()
{
// todo: add your command handler code here
oddbdatabase* pdb = getdocument()->m_pdb;
pdb->startundorecord();
oddbblocktablerecordptr pms = pdb->getmodelspaceid().openobject();
oddbblocktableptr pt = pdb->getblocktableid().safeopenobject(oddb::kforwrite);
oddbsymboltableiteratorptr ptit = pt->newiterator();
while(!ptit->done())
{
oddbsymboltablerecordptr psymrec = ptit->getrecord(oddb::kforwrite);
oddbobjectiteratorptr pentiter = oddbblocktablerecordptr(psymrec)->newiterator();
while(!pentiter->done())
{
oddbentityptr pent = pentiter->entity(oddb::kforwrite);
pentiter->step();
if (!pent.isnull()
&& (pent->iskindof(oddbregion::desc())
|| pent->iskindof(oddbbody::desc())
|| pent->iskindof(oddb3dsolid::desc())))
{
bool exchangexdata;
oddbobjectid replaceid;
oddbobjectptr pnewobj = pent->decomposeforsave(oddb::vac12, replaceid, exchangexdata);
if (!pnewobj.isnull())
{
pent->handoverto(pnewobj);
oddbentityptr pe(pnewobj);
if (!pe.isnull())
pe->setpropertiesfrom(pent);
}
}
}
ptit->step();
}
filltree();
thanks a lot, like that it works fine.
i just have a question, why do we have to set again the properties to pent like that?
code:
oddbentityptr pe(pnewobj);
if (!pe.isnull())
pe->setpropertiesfrom(pent);pent before those lines seems to have already the right properties.
