Abstract

This article analyzes specific creation features of automated design the hydro-technical sluice system. An engineer frequently designs the hydro-technical structures. This work is done faster if special programming procedures for calculating and visualizing graphical objects are used. The creation tasks of the hydro-technical sluice automated design system are solved with Unified Modeling Language. Modeling separates four types of models: use case, behavior, class and implementation. Every model is visualized by one or more types of diagrams. Graphical system can select pipes depending on the type of water flow, form the roadbed by the sluice parameters, calculate panels according to the option type and design two hydro-technical structures views. It discerns objects-classes: pipe, roadbed, panel, which have some properties and methods that ease programmer’s work. The hydro-technical structures altitudes and water flow parameters are known. First, program selects diameter of pipe from standard pipes database by using ActiveX Data Objects technology, which by programming method connects drawing and database. Drawing’s graphical objects have additional data from which exchange of data between graphical system and database is executed. Second, roadbed geometry is calculated using programming object’s properties and methods. Third, the program knowing pipes’ and roadbed’ geometry designs panels. Integrated CAD environment (AutoCAD) with Visual Basic Application programming language enlarges possibilities in engineering design. Design system and example of the hydro- technical sluice project with specifications is presented. Specific creation features of automated design system are discussed and conclusions are made.
