In this dissertation , on the basis of the analysis of the dimension effect of engineering drawings , a dimension model based on functional semantics is advanced . a new scheme for constructing and adjusting the initial dimension model is put forward , meeting the dimensioning requirement of integrality and rationality 本文在分析工程圖紙尺寸作用的基礎(chǔ)上,建立了基于功能語(yǔ)義的尺寸模型,介紹了尺寸模型的初始生成方法,提出了尺寸模型的調(diào)整策略,從而滿足尺寸的完整性和合理性要求。
In chapter 1 , the thesis discusses the meaning and current research status of automatic dimensioning . then a three - level strategy of automatic dimensioning based on the dimension model is proposed , and the significance and feasibility of the dimension model based on functional semantics are explained 在第一章中,討論了尺寸自動(dòng)標(biāo)注研究的意義,分析了國(guó)內(nèi)外這一課題的研究狀況,提出了基于尺寸模型的三層次尺寸智能標(biāo)注策略,并闡述了功能語(yǔ)義尺寸模型的研究意義及其可行性。
In chapter 2 , the thesis discusses differences and connections between the dimension model and the dimensioning model . on the basis of the analysis of functional semantics of dimensions , a dimension model based on functional semantics is developed , and its four levels are defined in detail : shaping level of functional semantics , locating level of functional semantics , machining level of functional semantics , assembly level of functional semantics 在第二章中,探討了尺寸模型與尺寸標(biāo)注模型之間的關(guān)系,在分析尺寸各種功能語(yǔ)義的基礎(chǔ)上建立了基于功能語(yǔ)義的尺寸模型,并詳細(xì)定義了尺寸模型的四個(gè)層次:定形功能語(yǔ)義層、定位功能語(yǔ)義層、加工功能語(yǔ)義層、裝配功能語(yǔ)義層。
Considering the shape expression modes are more diversiform , dispersed , and complex in shop drawing , many notations in shop drawing contain shape information , also with distinct characteristics , a new method of extracting engineering quality based on notation entities functional semantics is put forward in chapter 5 建筑圖樣形體形狀的表達(dá)方式豐富、多樣,建筑圖樣的很多標(biāo)注中蘊(yùn)涵形體的形狀信息,并且這些標(biāo)注具有明顯的視圖特點(diǎn)。論文第五章通過分析施工圖中的標(biāo)注和建筑物功能部件的關(guān)聯(lián)特征,提出了基于標(biāo)注實(shí)體功能語(yǔ)義的工程量信息獲取方法。
