Area moment of inertia and coordinate system

I'm using SolidWorks to verify some calculation of centroids and area
moments of inertia. In doing so I sketch on the front plane and
position the sketch with respect to the coordinate system, the same
way as in my calculations. When extruding the sketch and subsequently
using Tools -> Section Properties the centroid always comes out
correctly and the same goes for the area moment of inertia about the
centroid axes.

SolidWorks also has output named: "Moments of inertia of the area, at
the output coordinate system". However this does not correspond to the
area moment of inertia about the x,y,z axes. I have tried to solve
this by adding my own coordinate system, but this doesn't change the
result of the SolidWorks calculation.

Does anyone here know how to get the "Moments of inertia of the area,
at the output coordinate system" to actually be the same as the area
moment of inertia about the x,y,z axes?

Thanks in advance.

 

Instead of moving your sketch around the base CSYS, create a new CSYS
where you need it. When you have additional CSYS's available, you can
select them in a combobox in the measure tool dialog.

 

Thank you for the reply. I have already tried this multiple times.
Placing the sketch whereever I see fit and then adding a new
coordinate system for fit my sketch. The result remains different from
the actual area moment of inertia.
