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

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
theSession->SetUndoMark();       
% T6 a+ g7 x* W2 J2 TtheSession->UndoToMark();
4 s8 h: f. ^/ @' PtheSession->DeleteUndoMark();
, j$ i. V; p9 `9 _( o1 f6 J这样是没问题的,速度又很快.
8 e' y' v: t! O9 [0 s+ w但是问题又来了:
. ^- c. A) T$ {0 v0 }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...

6 K8 G. d) F$ o/ wm_pTextObject 这个nxobject对象如何使用到后面拉伸所用的截面线的呢？需要转化？
