. ]( B* n5 O: y3 W8 A0 g$ s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。0 h. }* F# y( d( g' C) v
我尝试过生成直线或圆弧,都没有这个问题。% D2 ^) u% Y& n% x8 }
