[ARX函数]：有什么函数可以关闭和冻结所有层？

qwweert

又怎么再打开某个层呢？

最简单的：
关闭
acedCommand(RTSTR,"layer",RTSTR,"off",RTSTR,"*",RTSTR,"y",RTSTR,"",0);
打开
acedCommand(RTSTR,"layer",RTSTR,"on",RTSTR,"*",RTSTR,"",0);
复杂的可用
AcDbLayerTable,AcDbLayerTableRecord类实现
//例子:
void OffAllLayer()
{
        AcDbLayerTable *pLayerTable;
        AcDbLayerTableIterator *pLayerTableIterator;
    acdbHostApplicationServices()->workingDatabase()
        ->getSymbolTable(pLayerTable, AcDb::kForRead);

        pLayerTable->newIterator(pLayerTableIterator);

        for(;!pLayerTableIterator->done();pLayerTableIterator->step())
        {
                AcDbLayerTableRecord *pLayerTableRecord;
                pLayerTableIterator->getRecord(pLayerTableRecord,AcDb::kForWrite);
                pLayerTableRecord->setIsOff(true);
                pLayerTableRecord->close();
        }
        delete pLayerTableIterator;
        pLayerTable->close();

}
