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->UndoToMark();
# F& J4 ?9 i$ Y% CtheSession->DeleteUndoMark();
; J6 Y3 N# j5 i; X, ~8 x) O3 U这样是没问题的,速度又很快.

, @2 Y% Z  h1 F- \- w  N& G* h: ?; ]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...

: i) {2 s: r1 t: u& o" q' ?m_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？
