问题：
我可以按照美国规范 AISI S100 或 CSA S136 设计用户自定义的（参数化）截面吗？
答案：
A custom section can be created using one of the “Thin-Walled” sections available in the library. For other sections that do not meet any of the 14 available cold-formed shapes, the sections can be created and imported from the standalone program, RSECTION.
Parametric (custom) sections with “Cold formed” manufacturing type can be designed according to AISI S100 or CSA S136.
