UF_MODL_ask_mass_props_3d
Returns the mass properties of the specified collection of solid or sheet bodies.
返回指定的实体或片体集合的质量属性。
Specify units and a density value, and either an accuracy value(set accuracy = 1) or relative tolerances (set accuracy = 2) for the mass property computations.
指定单位和密度值，以及质量属性计算的精度值(设置精度= 1)或相对公差(设置精度= 2)。
For simple analytic solid or sheet bodies (e.g., planes, cylinders), an accuracy value of 0.9 is sufficient. For more complicated solids or B-Surface sheet body faces, accuracy values closer to 1.0 may be necessary.
对于简单的分析实体或片体(例如，平面，圆柱体)，0.9的精度值是足够的。 对于更复杂的固体或B-Surface板体表面，精度值接近1.0可能是必要的。
If Relative Tolerances are specified, the system iterates on accuracy values until successive mass property values are within the specified relative tolerances.
如果指定了相对公差，则系统对精度值进行迭代，直到连续的质量属性值都在指定的相对公差内。
The relative tolerance values are defined by the test value (or estimated relative tolerance) is where MP(n) is the mass property value for the n-th iteration on the accuracy value.
相对容差值由测试值(或估计的相对容差)定义，其中MP(n)为对精度值进行第n次迭代的质量属性值。
If a relative tolerance of 0.0 is specified, no testing is done for the corresponding mass property value, although all the mass property values are computed using the same accuracy values.
如果指定了相对公差0.0，则不对相应的质量属性值进行测试，尽管使用相同的精度值计算所有质量属性值。
怎样把给定密度带入到UF_MODL_ask_mass_props_3d计算中？
晕，怎么都不看函数说明呢，明明说得很清楚啊。那个density是你输入sheet body的时候，才有用的，对于solid body，就用每个solid 自己的density，最后输出的density是平均的density。
设置body 的density的函数：UF_MODL_set_body_density
double
UF_MODL_set_body_density
在UG中哪个函数可以得到实体的体积啊？
三维图形的中心
UG中求实体形心的函数是什么？
UG二次开发怎么求质心的坐标？
UG二次开发中 获得面积函数
获得面积函数：
UF_MODL_ask_mass_props_3d
一般先使用函数 UF_MODL_extract_face 提取面抽取面后再使用获得面积函数
UGopen 获得对象信息、面积体积等函数说明
对象信息、面积体积等等
UF_MODL_ask_mass_props_3d
获得面积要先抽取面才能获得。
