难道算术约束设置是把双刃剑?

在模型建立时我们可以通过Property/Constraint菜单下的set arithmetic constraint 向我们的对象设置算术约束条件.例如:/F
K-I
l L/m4V0c
{if (perm < 0) perm=0;}
tU2}Vh
\[FA{ {if (position<0) position = -1; else position = cell (position);}

在usermannual中有如下的解释和警告

can only add more restrictions but not remove them.

不知道,新版的gocad对于set constraint 功能的实现是否已经完善.看起来似乎在2.0.8中,这是把双刃剑.
