More and more large structures are generally transported at sea by barge,and barge loading distribution is an important procedure before transportation.General loading distribution system has powerful capability of calculation;however,it has little or no capability of drawing the loading distribution plans.The way of enhancing the capability of drawing of barge load distribution system in virtue of external drawing software is brought forward for the weakness of barge load distribution system.Namely,loading distribution system can automatically generate the loading distribution plans by directly reading calculation results of the system and other related data files with the tools of VBA and ActiveX of AutoCAD2002,which can enhance the capability of drawing of barge load distribution system.Then automatic loading distribution of barge from calculation to drawing is implemented.Several examples are presented,which illustrate the feasibility and the validity of the way.
