在Creo6环境中，ProToolkit C++进行多次钣金展平操作，Creo崩溃
在Creo6环境中，使用ProToolkit C++开发工具进行钣金展平操作，执行多次后有概率导致Creo遇到严重错误并弹出“自动回溯信息”窗口，点击窗口后Creo自动退出。
钣金展平部分代码如下：

In Creo6 environment, ProToolkit C++ performs multiple sheet metal flattening operations, Creo crashes.
In the Creo6 environment, use the ProToolkit C++ development tool to perform sheet metal flattening operations.
After multiple executions, there is a possibility that Creo encounters a serious error and pops up the "Auto Traceback Information" window. Creo automatically exits after clicking the window. The code for the sheet metal flattening part is as follows:
