基于三维设计的钢筋图自动标注

Automatically dimensionmarking drawings of reinforcing steel bar based on 3-D design

为将人从琐碎的制图活动中解脱出来,在水工结构三维可视化系统中,研究了钢筋自动标注技术.建立了标注抽象模型和标注实体信息模型,详细叙述了钢筋图自动标注及标注干涉自适应调整的实现方法,形成了一套标注干涉检查程序.系统在工程中的应用表明,运用该方法自动生成的钢筋图标注信息正确、清晰、合理,达到了施工图的要求.

The technique of automatically dimension marking dimensioning drawings of reinforcing steel bars in 3-D visualized system of hydraulic structure was studied to free engineers from tedious drawing activities. The methods for automatically dimensionmarking drawings of reinforcing steel bar and realization of the self-adaptative adjustment of marking collision were expounded. A standard abstract model and a dimension marking model were established, and a set of standard marking collision detection program was formed. The application of the system shows the method is correct, clear, and reasonable in automatic generation of drawings of reinforcing steel bars and related marking information, and the requirement of construction design can be met.
