1、東南大學(xué)碩士學(xué)位論文摘要隨著計(jì)算機(jī)硬軟件技術(shù)的飛速發(fā)展,涵洞CAD技術(shù)也取得了很大的進(jìn)步。國(guó)內(nèi)現(xiàn)有很多各具特色的涵洞CAD軟件,但它們?cè)谑褂弥芯嬖诓煌潭鹊牟蛔恪a槍?duì)這些問題,,f:考慮到涵洞設(shè)計(jì)本身的標(biāo)準(zhǔn)化、規(guī)范化,本文研究了涵洞參數(shù)化設(shè)計(jì)與繪圖的方法,并利用ObjectAtLX和MFC相結(jié)合進(jìn)行了涵洞CAD系統(tǒng)的開發(fā)。在程序開發(fā)方面,本文首先對(duì)涵洞設(shè)計(jì)數(shù)據(jù)進(jìn)行了分析,然后采用了面向?qū)ο蟮姆椒?,定制了涵洞類,描述了類之間的層次關(guān)系.探討了數(shù)據(jù)的傳遞方式。根據(jù)不同的涵洞類型,開發(fā)?不同的設(shè)計(jì)模塊。在工程圖繪制方面,應(yīng)用了參數(shù)
