Utilizing Entity Data to Numerically Sheet a Single Arbitrarily Pipeline
Jing Zhang, Meng Qing-yao · 2004
In AutoCAD,we can utilize the speciality of rulesurface to numerically sheet a single pipeline which shape of both sides are different,and realize that the shape and position of both sides are arbitrary.Then we compile programs in LISP to estabilish a friendly user interface——Dialogue-box.Not only calculating and drawing automatically can be formed,but also the accuracy of sheeted drawing and the work efficiency can be enormously improved.
