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:

void Letter::textProcess(const char * fonTContent, char* fontType, double& wScale,bool bools)
{
if (m_pTextBuilder == NULL)
  m_pTextBuilder = m_pTextBuilder = workPart->Features()->CreateTextBuilder(m_pNullNXOpen_Features_Texts);
int i = 0;

m_pTextBuilder->SetFontStyle(NXOpen::Features::TextBuilder::FontStyleOptions::FontStyleOptionsRegular);
m_pTextBuilder->SetOrientationMethod(NXOpen::Features::TextBuilder::OrientationMethodOptions::OrientationMethodOptionsNatural);
NXOpen::Features::TextBuilder::ScriptOptions characterSet;
if (fontType[1] >= 'A'&&fontType[1] <= 'z')
  characterSet = NXOpen::Features::TextBuilder::ScriptOptions::ScriptOptionsWestern;
else
  characterSet = NXOpen::Features::TextBuilder::ScriptOptions::ScriptOptionsGb2312;
i = 0;

预览就是你先commit 生成，然后设置下透明度而已

浮游 · 发表于 2015-8-25 17:56:35

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();
theSession->UndoToMark();
theSession->DeleteUndoMark();
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 · 发表于 2015-8-25 18:07:59

...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...

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？

要预览的代码你放在哪里，我放在update中，但是生成的模型无法再撤回了，求指点一下
