Reinforcement detail drawings are one important part of the design of hydraulic structures and the important basis of construction and management. However, the efficiency of the traditional creation of engineering drawings is very low and the workload is heavy. There is no satisfactory software for hydraulic engineering because of the irregularity and diversity of hydraulic structures' shape. An automatic generation system of reinforcement detail drawings for hydraulic structures is introduced. Its functions and modules are introduced first. The related technologies such as automatic driensioning are discussed in detail. At the end of the paper, an example is given. 展开更多
