我在线面建立了一个创建直线的程序 部知道怎么区使用何调用它
给出创建源代码:AcDbObjectId
createLine()
{
AcGePoint3d startPt(4.0,2.0,0.0);
AcGePoint3d endPt(10.0,7.0,0.0);
AcDbLine *pLine=new AcDbLine(startPt,endPt);
AcDbBlockTable *pBlockTable;
acdbHostApplicationServices()->workingDatabase()
->getSymbolTable(pBlockTable,AcDb::kForRead);
AcDbBlockTableRecord *pBlockTableRecord;
pBlockTable->getAt(ACDB_MODEL_SPACE,pBlockTableRecord,
AcDb::kForWrite);
pBlockTable->close();
AcDbObjectId lineId;
pBlockTableRecord->appendAcDbEntity(lineId,pLine);
pBlockTableRecord->close();
pLine->close();
return lineId;
}
那位知道怎么在主函数中区调用它 并能在CAD中画出一条直线.
