如图，我怎么确定圆柱在四方体上的位置？标的尺寸不能修改的
菜鸟，请多包涵

haubest

先选中圆柱体图素，再表尺寸即可修改。如果是放在中心，拖放时直接可以放到中心。

azhang

是选择问题，要移动圆柱体，只能先选中这个圆柱体，不能两个都选中(对着再圆柱体再多点一下)，再标智能尺寸，然后编辑尺寸

azhang

其实这也体现了我以前说的一个重要原则-----零件只能自我约束

haubest

我认为实体设计更主张使用三维球定位，使用尺寸约束在实体设计中不是一个好方法。

lydyy

那么我定位圆柱体在长方体上的位置只能先把圆柱体拖放到长方体的边的交点，在利用三维球定位吗？

haubest

不是只能利用三维球，而是可以利用三维球。当然也可以利用智能尺寸定位，还可以利用像其他软件的坐标定位。
