4 y, h! E& ~' s7 {" W+ n我想用NX Open C++编个简单的外部程序生成一条Studio Spline曲线,直接用操作记录稍微改了一下。程序没有报错,但是调试的时候在“studioSplineBuilder1->CommitFeature()”这句(代码倒数第九行)跳出来这个中断:“***.exe 中的 0x2031f7eb 处未处理的异常: 0xC0000005: 读取位置 0x00000000 时发生访问冲突”(Unhandled exception at 0x2031f7eb in test.exe: 0xC0000005: Access violation reading location 0x00000000.)。请大牛指教。
5 u' Y, I: g$ B! J& b1 e我尝试过生成直线或圆弧,都没有这个问题。
