..............
if (strcmp(pcname, "acdb3dpolyline")==0)
{
acdb3dpolyline *pline;
pline = acdb3dpolyline::cast(pentity);
acdbobjectiterator* pverietor;
pverietor = pline->vertexiterator();
pline->close();

acdb2dvertex *pvertex;
acgepoint3d pt;
acdbobjectid vertexobjid;
for(pverietor->start(); !pverietor->done(); pverietor->step())
{
vertexobjid = pverietor->objectid();
acdbopenobject(pvertex, vertexobjid, acdb::kforread);
/// ////////////////////
// pvertex->close();
}
}
为什么这段代码在红色处运行出错？
