The system depends on the features of rapidness , simplicity , driving by parameter and fitting for designers ’ habits and blends the size parameter into data structure and by using the driving technology realizes the drawing of single and double track lines of inter - station and the plane arrangement maps of station contact net 該系統依賴參數化方法所具備的快速、簡潔、參數驅動、符合設計者習慣等特性,將尺寸參數融入到數據結構中,利用尺寸驅動技術實現尺寸約束,實現區間單、復線和站場接觸網平面布置圖的繪制。

Landscape city kang taixing the fire fighting equipment limitedcompany , is situated at zhejiang , fujian , in the jianxi threeprovinces borders landscape city xintangbian fire preventionindustry garden area , the transportation is convenient , the road abuts205 federal highways , is apart from the track line 8 kilometers , isapart from the chu chou airport only 60 kilometers 江山市康太星消防設備有限公司,地處浙、閩、贛三省交界的江山市新塘邊鎮消防工業園區內,交通方便,公路緊靠205國道,距鐵路線8公里,距衢州機場僅60公里。

The main principles of this new approach are : 1 ) find out the track line segments for vertices of one polygon to another polygon ' s edges ; 2 ) get the enclosing polygon and internal clockwise loops that was formed by the track line segments , finally the result polygons are the final nfps 該算法的基本原理是: 1 )求解多邊形頂點相對于另一多邊形的軌跡線; 2 )求解軌跡線集合所形成的外包多邊形和內部順時針環,得到的多邊形即為臨界多邊形。

In this paper , the problem of calculating movement of piece is simplified to the problem of finding track line segments between vertices and edges , hence the time complexity is much reduced , and special cases such as inner cavity and inner nfp ( no fit polygon ) can also be tackled 摘要將多邊形滑動碰撞問題轉化為頂點和邊之間的軌跡線提取問題,從而降低了時間復雜度,并可統一處理邊界空腔和內部靠接臨界多邊形問題。
