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
theSession->SetUndoMark();       
' i4 }0 I, t6 w' S% K  C  ftheSession->UndoToMark();
theSession->DeleteUndoMark();
7 m7 G$ U5 h* H; D7 \2 W这样是没问题的,速度又很快.
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...

/ o6 ?4 k6 T4 A7 X9 w- K/ Xm_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？
