以ProE软件为平台，研究了复杂形状容器的体积与高度的变化规律，并以食用油桶为例，利用ProE行为建模模块中的“UDA”分析功能、Pro/Program 模块中的程序编辑以及曲面模块，在容器表面智能化地刻制3D刻度线以及标示容积大小的3D文字，有效地解决了容器容积的标示问题，保证了容器容积的标示精度，提高了刻度容器的设计与加工的效率。该方法可应用于复杂容器容积的计算和刻度线的设计制作。

The changing rule of vessel's volume with correspondence high of complex containers was studied using ProE software. Edible oil drum was taken as example. The vessel volume indication method has solved effectively with the UDA analysis function in ProE behavior modeling module, the surface module formidable function and procedure edition function in the Pro/Program to intellectually mark 3D volume's scale as well as indication volume 3D character in the vessel surface. This can guarantee volume precision and enhance efficiency of vessel design. The method can be widely applied in complex vessel volume computation, scale division line design and manufacture.
