这个面建立的不对，因为你之前的面定义的参数导致在X方向的面具有一定的偏差，也就是误差太大，导致后面的就没有办法布尔操作了，你这个面要根据已经定义好的面所在的坐标来创建，如果后面要继续你之前的操作完成，你的建模方式就要变了

你也可以在减之前FLST,2,1,5,ORDE,2

输入BTOL,10，把公差调整大一点，就可以继续了，但是精度不是很好
以后建模希望几何参数的有效数字不要超过6位，还有要定义好好所在平面，不要偏差太大，，慢慢理解下

追问

为什么会在x面上产生误差，x坐标都是一样的

追答

呵呵，也不一定是X方向，但是可能性最大，因为你的面是垂直X的

追问

除了改btol还有其他方法吗,怎么才能把有问题的这个面修改好

追答

重新建模，那就需要比较扎实的经验了，用改公差只是一个折中的办法
