怎样插入文件块?
我用下面的代码插不进去
acdbobjectid blockid ;
acdbdatabase *pdb=new acdbdatabase(adesk::kfalse);
pdb->readdwgfile(name);
blockid=pdb->xrefblockid();
acdbblockreference *pblkref =new acdbblockreference ;
pblkref->setblocktablerecord (blockid) ;
pblkref->setscalefactors(acgescale3d(scale,scale,scale));
pblkref->setposition(pt) ;
pblkref->setrotation (rotation) ;
acdbblocktable *pblocktable ;
acdbhostapplicationservices()->workingdatabase()->getblocktable (pblocktable, acdb::kforread) ;
acdbblocktablerecord *pblocktablerecord ;
pblocktable->getat (acdb_model_space, pblocktablerecord,acdb::kforwrite) ;
pblocktable->close () ;
pblocktablerecord->appendacdbentity(pblkref);
pblocktablerecord->close();
pblkref->close()
这代码我是在人家那里看到的,怎么不行呢?
//读test.dwg文件以mydrawing块名插入打开文件
void readdwgfile()
{
acdbdatabase *pdwg =new acdbdatabase (adesk::kfalse) ;
pdwg->readdwgfile(l"c:\\test.dwg");
acdbobjectid blockid ;
acad::errorstatus es = acdbhostapplicationservices()->workingdatabase()->insert(blockid, l"mydrawing", pdwg, adesk::kfalse) ;
if ( es != acad::eok )
acutprintf (l"\n插入块错误.") ;
delete pdwg ;
//上面创建了“名字是myfile的块定义acdbblocktablerecord”，
//objectid是blockid，接着就可以实例acdbblockreference对象，
//创建insert实体了。
acdbblockreference *pblkref =new acdbblockreference();
pblkref->setblocktablerecord (blockid) ;
//---- 设置插入点，旋转角度，比例等等
pblkref->setposition(acgepoint3d(0.0,0.0,0.0)) ;
pblkref->setrotation(0.0);
//....最后把上面的块索引对象添加到数据库里面
//获得模型空间块表记录
acdbblocktable *pblocktable;
acdbhostapplicationservices()->workingdatabase()->getblocktable(pblocktable,acdb::kforread);
acdbblocktablerecord *pblocktablerecord;
pblocktable->getat(acdb_model_space,pblocktablerecord,acdb::kforwrite);
pblocktable->close();
//----- 添加块引用pblkref实体到模型空间
acdbobjectid newentid ;
pblocktablerecord->appendacdbentity(newentid, pblkref);
pblocktablerecord->close();
pblkref->close();
}
