exploding 3dpolylines
exploding 3dpolylines
with dd 2.1.0 exploding 2dpolyline gives a set of lwpolylines
but
exploding a 3dpolyline returns a 3dpolyline.
here is the code i use :
//================================================== ===========================
void importer::convert3dpolylines(player pthelayer,oddbentityptr pent)
//================================================== ===========================
{
odresult odres;
odrxobjectptrarray pentityptrs;
bool bempty;
int inbelements,i;
odrxobjectptr pexplodedentity;
odres= pent->explodegeometry(pentityptrs);
bempty= pentityptrs.isempty();
if(!bempty)
{
inbelements= pentityptrs.length();
for(i=0; i< inbelements; i++)
{
pexplodedentity= pentityptrs[i]; // first
displayentityname((oddbentityptr) pexplodedentity);
convertentity(pexplodedentity,false,null,-1,false,null );
}
}
i would expect that exploding a 3dpolyline returns a set of 3d lines..
is this a kown issue ?
thanks
explodegeometry() calls entity's worlddraw() and makes db entities of geometry primitives called from worlddraw(). single polyline in cases of oddb3dpolyline.
in order to get lines from oddb3dpolyline you need to call explode() or explodetoblock().
