Based On The Weft To Interchange Design Aided Design Functions Of Software Development

As an important part of highway interchange, and the pros and cons of the design resultswill directly affect the operating condition of the highway. In the linear design of interchange,and domestic design software used with weft (HintCAD) software, EICAD road, road Dicadpro software escorting, Germany, etc. At present domestic design market interchange, weftsoftware share the highest, is the highest utilization rate at present road design of the software.This article based on the weft (HintCAD) interchange design software function deficiency, inthe detailed analysis of weft interchange design features and characteristics, on the basis ofstudy of weft interchange design software auxiliary function development and the keyalgorithms.Batch is proposed in this paper automatic search connection interchange of feature points,and proposes the improved binary legal point for pile and connection of interchange featurepoints batch automatic search method and process of the mass production of each connectionfunction can be automatically (hui) flow points, points (hui) flow nose, big nose, etc., at thesame time automatic recording files, search and display width change these feature pointslocation, and can handle ramp at the same time a variety of connection types of multipleconnections of analysis and calculation. Proposed the ramp profile automatically transfer thefunction of slope design and generate the initial profile. The batch automatic search functionbased on the connection of feature points automatically complete the ramp profile slopecalculation and generate a conform to the requirements of the two ends of slope of the initialline of profile design, the ramp profile design without consideration on both ends of the slopeproblem, and automatic calculation based on intersection calculation function, insert anddisplay profile control points. Finally, put forward the automatically set up and modify theinterchange mainline and ramp width files within the scope of functions, and put forward theautomatically set up and modified within the scope of interchange mainline and ramp widthmethod and process of files.
