斑竹请进，急，

我现在做动力学仿真，measue了三个角度，然后在postprocessor用spreadsheet导出转角数据，我看了你前面的例子，从view里的import这些数据，create culve，然后在motion里用AKISPL(time,0,SPLINE_6, 1)*time，但是机构的动作不是要求的那样，不知道怎么回事，节选一些错误提示如下：

   SPLINE scenario_2.SPLINE_6. Out-of-range X and Z values of spline have been used more

请斑竹和各位高手指点迷津

嗯
角度的测量是角度的，如果在定义motion的时候没有定义为角度的话，一定按照弧度去计算了。

角度转换的函数是rtod^_^

rtod怎么用阿，没用过，谢谢了，不好意思，可能就是那么回事

就是对角度和弧度进行转化,如果你不熟悉那个函数的命令,那么就用3.1416作为圆周率派,在定义数据的时候自己进行计算就可以了.  3.1416rad=180"  进行转

我原来测出来的角度就是角度制的，比如测出来10度，这里却变成10弧度，不是比例关系的变化，10*180/3。14不等于10度啊，郁闷

就照你楼上的去改 ，就是了
