CST MWS建的模型，想要切掉一部分怎么做啊？

把要切得部分也画出来 然后 BOOLEN-SUBSTRACT

SUBSTRACT 只是两物体相交后  的相减啊  我的意思是直接建出的模型 只要一半呢?

Slice by UV Plane -> Delete

小编留言：

谢谢您的指导 不过我找了找 怎么没有找到Slice by UV Plane -> Delete

楼上的办法最简单。

这牵扯到几点：
1、你的局部坐标系出来了吗?
2、局部坐标系的UV面是否已经是正确的?即UV面就是要切的平面?
3、先选中你要去切的物体，再去objects里面看Slice by UV Plane是不是亮了，然后点一下这个键。
4、这样操作完了，只是物体被UV面切开了而已，你要自己选中要删除的那部分，点击Delete。
建议以后遇到这样的问题，先到Help里搜索一下“Slice”这个词眼

非常感谢小编
，另外我是软件安装后发现 help 文件没有安装进去 后来再点击也没有文档了

1: first, you need to make sure of which plane you would like to use to cut the object.
2: pick face, and active the WCS and align it on the selected face (plane)
3: Normally, the UV plane of WCS should overlap with the selected plane of the object, if it didnt, please rotate it by choosing the proper angles to make it happen.
4: Click the object that you wanna cut in the navigation tree, then go to the "object" tool and now you will see a highlighted button "slice by UV plane", click OK
5: Now you can see there is an extra object (the one that you've cut) on the list of navigation tree. canel it
6: Done
PS: I can only type English  from my company's computer, hope it would do some help to you
