由G.BOOTHROYD开发的能量屏障法用于计算零件自然静止状态的概率，除了最简单的横截面形状外，对所有形状都有计算要求，并且需要对能量屏障的形式进行清晰的可视化。这种方法变得冗长而笨拙，尤其是对于不规则形状。本文提出了一种图形化CAD替代方案。

THE ENERGY BARRIER METHOD, DEVELOPED BY G. BOOTHROYD TO COMPUTE THE PROBABILITIES OF NATURAL RESTING ASPECTS OF PARTS, IS COMPUTATIONALLY DEMANDING FOR ALL BUT THE SIMPLEST CROSS-SECTIONAL SHAPES, AND REQUIRES A CLEAR VISUALIZATION OF THE FORM OF THE ENERGY BARRIER. THE METHOD BECOMES PROTRACTED AND UNWIELDLY ESPECIALLY FOR IRREGULAR SHAPES. A GRAPHICAL CAD ALTERNATIVE IS PROPOSED IN THIS PAPER.
