CST MWS建的模型，想要切掉一部分怎么做？

CST建的模型，比如做出來的圓環面 ，怎么只需其中一半，而將其他的除去啊?
新手上路，望大俠們指點啊 謝謝啊

把要切得部分也畫出來 然后 BOOLEN-SUBSTRACT

SUBSTRACT 只是兩物體相交后 的相減啊 我的意思是直接建出的模型 只要一半呢?

Slice by UV Plane -> Delete

小編留言：

謝謝您的指導 不過我找了找 怎么沒有找到Slice by UV Plane -> Delete

樓上的辦法最簡單。

這牽扯到幾點：
1、你的局部坐標系出來了嗎?
2、局部坐標系的UV面是否已經是正確的?即UV面就是要切的平面?
3、先選中你要去切的物體，再去objects里面看Slice by UV Plane是不是亮了，然后點一下這個鍵。
4、這樣操作完了，只是物體被UV面切開了而已，你要自己選中要刪除的那部分，點擊Delete。
建議以后遇到這樣的問題，先到Help里搜索一下“Slice”這個詞眼

非常感謝小編
，另外我是軟件安裝后發現 help 文件沒有安裝進去 后來再點擊也沒有文檔了

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
