Hello. I'm having trouble with the moments of inertia in the section properties.


I hav this part which is a standard structural steel profile. As you see in the image, Ix and Iy , as the part is symmetrical, is listed in both cases as 10500 (I don't know the unit, but I take it as the correct number since other catalogs list it as 1050 cm4).

Now, when I check the same thing in the section properties, it lists other moments of inertia (I see the "main" ones are defined in a slanted axis system), but none are 10500 or anything of the sort.

How do I go about getting the correct Ix and Iy from the section properties? I already tried using other axis system that isnt slanted but I also dont get the correct numbers.

Thanks in advance.
