| Road profile drawing is the find result of road profile design and one of the important documents for road designing.The profile drawing consists of two parts, upper part and lower part; On the upper part, ground line and design gradient line are drawn , and the elements of vertical curves, the sites and types of bridges, culverts and other structures along roads are noted. On the lower part, straight-lines and horizontal curves, mileage stake, ground elevation . design elevation, fill and cut depths, gradient and grade length, and geological situations are filled and written. Hence, profile contains a lot of road design contents, Road profile not only clearly expresses design results, but also.meets the requirements of different drawing sizes and patterns in the specific road works design, and made the design result standard and beautiful.Traditional profile drawings are made by handwork, that takes a lot of time and work, and the result is not pretty and its quality is not good but flexible; based on Auto CAD. profile drawing software developing greatly elevate drawing efficiency, made drawing quick and beautiful, but flexibility is not very good.Based on the idea of object-oriented, this paper has designed the road profile drawing software , developed profile drawing software based on Auto CAD2002. by adopted dialogue frame technique of MFC (provided by Microsoft) and object ARX2000 (provided by Autodesk).second time Developing technique. Several key contents such as the classes definitions and dialogue frame was illustrated.This paper tried to solve the problem of drawing automation, flexibility and expansiveness for afterwards. The final software was proven correct and easily-used by some tests for read road projects. Because the software was framed as an open structure , it is easy to added or adjusted some drawing contents in application. |
