本論文是在AutoCAD繪圖軟體下,用參數式方式以 Visual LISP語言撰寫程式自動建立視圖,並配合螢幕驅動多層多頁之方法來設計畫面,發展出一套自動快速繪圖的架構系統以繪製各種零件,發展出一套標準零件庫繪圖系統,以幫助AutoCAD製圖人員在進行2D標準模具零件的工程圖繪製時,能夠更有效率而準確的完成製圖任務。 螢幕驅動頁有多頁以及多層之功能,每頁繪圖區範圍可任意分割成X*Y之驅動格數,每一個驅動格可執行一項單獨之任務,另外配合參數化的繪圖程式設計,使用者只需經由幾個簡單的參數點選動作,即可快速地完成標準機械零件圖形的繪製。 軟體介面不同於一般視窗環境下之操作介面如下拉式功能表( Pull-down Menu )或功能表上的小圖像(Icon),其只能提供使用者簡短的文字或部分的意象說明。本系統充分利用AutoCAD整個螢幕繪圖區當作驅動範圍,配合清晰的圖形及說明文字製作成圖像幻燈片驅動頁,可以將欲執行之繪圖任務展示在廣大的螢幕空間,以提供使用者在操作時能夠有更充分而完整之說明。
This thesis uses Visual LISP programming language and the multi-page and multi-layer screen-driven method to develop of mainframe system for auto drafting under the AutoCAD drafting software. With the parameter formula, the program can create the 2D projection views of the components automatically. By this system, AutoCAD users can do their two-dimensional drafting job of mechanical standard part more accurately and efficiently. The screen-driven regions are designed to have the functions of multi-page, multi-layer, and any (X * Y) number of driving blocks on each driving page. We use the Visual LISP programming language with the parametric approach to finish standard part automatically. The user can better the drafting speed by using it, and all they have to do is to pick the driving block. The interface of the drafting system differs from the pull-down menu and the icons which can only provide incomplete exposition in the common Windows application software interface. This system uses the whole drawing area of AutoCAD as the screen-driven region to show the driven page with slides, which leads the user by clear figures and exposition during the drafting process.
