Calculate Moment of Inertia?

[Anonymous]

I need to calculate the change in moment of intertia due to modifing a simple angled beam from 120 x 120 x 10 to 120 x 112 x 10.  Inventor has a function for moments but it rotates the center plane to something like VxV in the link below.  Is there a way to calculate this to X-X?  The instructions on this function are not very clear to me.  I'm also no expert with Inventor.  Thanks

Hi Folks,

There was indeed a regression in 2021 and 2022 (compared to 2020 and earlier). The area MOI in Cross Section Analysis double-counts. It was reported as INVGEN-57723. We are in the process of integrating the fix to 2021 and 2022 updates.

Hi @joshua.nenadich,

For assembly MOI, open the assembly and go to the browser -> right-click on the assembly icon -> iProperties -> Physical -> Update. The MOI should be shown at the bottom of the dialog.

Many thanks!
