sth is so X as to Y 与 sth is so X that Y

不知道是不是记混了，sth is so X as to Y 是否有这个句型啊?
我记得如果to后边动作发生是sth，sth is so X as to Y 是不是比sth is so X that Y 简洁？

俺在MANHATTAN SC的chapter 9中看到的so... as to的用法的解释，也大多认为是Wrong或者suspect，是种不被推荐的使用方式

Hello, 是不是我没有表达清楚。

sth is so X as to Y  如果 to后边动词主语为sth，那此句型是否比sth is so X that Y 简洁？

或者根本没有sth is so X as to Y 这个句型？
