标题: 【讨论】SPline Curvature Rate Control
Hi all,
  
1) how to control the curvature rate of a spline in ProE numerically ?
  
2) How to get a best smooth curve or ensure the curve having the curvature i want ? Not only by visual.
  
Many thanks for any idea.

Hmmm...i think this cannot be done in ProE, last time i was told by a PTC agent say it can be done, cheated i guess .

I know what you mean.
But I didn't find any solution till now.
The way that I do is adjusting the curvature number at the end ( in ISDX )
And let them look similarly,not accurately.

我用bmx做了一个研究,基本上可以达到你的要求,不过有点繁:
    1)建立一个曲率的测量分析,增加两个参数:MAX_CURV(最大曲率),MIN_CURV(最小曲率)。
   2)建立一个关系:delta=MAX_CURV:FID_ANALYSIS1-MIN_CURV:FID_ANALYSIS1
   3以MAX_CURV=某直(你想要的),DELTA为最小为目的,spiline的插入点坐标为变量进行最优化分析得到结果
  
敏感度分析有点繁,点越多越不好控制。
