问题：
如何在木结构设计模块中手动调整NDS和CSA O86系数？
答案：
For the CSA O86 and NDS 2018, the Modification and Adjustment factors can be manually adjusted with respect to the calculations run by the Timber Design add-on in RFEM 6. For both, these factors are tied to the material.
First, open the material(s) being used in the design and set them to "User-Defined". Once this is done, navigate to the Timber Design tab where the Modification and Adjustment Factors can be entered manually.
