急求如何创建新图层?

AcDbLayerTableRecord* pNewLayer = new AcDbLayerTableRecord;
//access the AcDbLayerTable pointer
pLayerTable->add(id,pNewLayer);
pNewLayer->close();

By the way, you'd better find answers in Arx help file before ask such question like this.

void createNewLayer(char* lyrname)
{
        // We need to check if the layer name exists
        // If the layer name exists, apply the color
        // linetype id and whither to make it current
        // or not. In order to be current it cannot be
        // frozen, so we need to check for this also.
        // If the layer name does not exist we just create
        // a new layer with the properties contained in the arguments

        AcDbLayerTable *pLyrTable;
        AcDbLayerTableRecord *pLyrTblRecord;
        AcDbObjectId recId;


        AcDbDatabase *pCurDb = NULL;

        pCurDb = acdbHostApplicationServices()->workingDatabase();


        pCurDb->getLayerTable(pLyrTable, AcDb::kForRead);
        // Check to see if the layer name exists
        if(pLyrTable->has(lyrname))
        {
                pLyrTable->getAt(lyrname, pLyrTblRecord, AcDb::kForWrite, Adesk::kFalse);
                // pLyrTblRecord now points at the layer table record
                // which was opened for write
                pLyrTblRecord->setIsFrozen(Adesk::kFalse);
                //                pLyrTblRecord->setLinetypeObjectId(ltypeId);

        }
        else
        {
                // Note how we can change the open mode
                // of the layer table from AcDb::kForRead
                // to AcDb::kForWrite

                pLyrTable->upgradeOpen();
                pLyrTblRecord = new AcDbLayerTableRecord;

                pLyrTblRecord->setName(lyrname);

                pLyrTable->add(pLyrTblRecord);

        }

        // Get the layer Table ObjectId
        recId = pLyrTblRecord->objectId();

        pLyrTblRecord->close();
        pLyrTable->close();

}
