二次开发NXOpenC++中NXOpen::Features::TextBuilder对象如何实现预览功

浮游

我是新人 想用TextBuilder辅助实现刻字功能,附上我自己克隆journal 的字体处理代码,还在修改中:

预览就是你先commit 生成，然后设置下透明度 而已

浮游

这个是不可行的,commit会生成一个实体的,这个不是我们想要的结果.其实我发完帖子不就之后就知道如何解决了.设置 撤销操作即可
( q- r' w: u& |- StheSession->SetUndoMark();       
2 P! Q. y4 v$ c" WtheSession->UndoToMark();
theSession->DeleteUndoMark();
4 q. a  J1 @6 M& k这样是没问题的,速度又很快.
1 m3 h) u$ [( G. N但是问题又来了:
在拉伸的时候出现 err:the tool and target do not form a complete intersection

浮游

...嘿嘿 我知道如何解决了 ,最后双向拉伸就好了 这是布尔运算造成的...
