Cm4

3D Design Volume Model

Hello, would there be a way to have the cm4 moment of inertia in the mass properties tab in solidworks?

The moments of inertia can be found in the "evaluate" tab in "Section Properties".

 

I think it's not possible to display this note in mass properties

Hi @ r.villeret

See these tutorials

Hello

By default, the properties contain the following info:

SW-Material

SW-Mass

SW-Density

SW-Volume

SW-SurfaceArea

SW-CenterofMassX

SW-CenterofMassY

SW-CenterofMassZ

SW-IX

SW-Iy

SW-Iz

SW-Px

SW-Py

SW-Pz

SW-LXX

SW-Lxy

SW-Lxz

SW-Lyx

 

Linking a note to a property should work by writing, for example:

$PRPMODEL:"SW-Lxx"

Is there a way to switch to cm4 instead of mm^4?

You need to change the units of your document: Tools/Options/Document Properties/Units/Custom. In the Length line in the Ground/Section Properties submenu, select centimeters. Then validate.

If this is a recurring need, modify your part and assembly models. Your old documents will keep values in mm. You will have to modify them as needed, or create a maccro to modify them en masse.
