Mass properties
Hello vscid,
SolidWorks treats imported parts (shell models) without mass properties and the centre of gravity will be where the origin of the model is.
You can however assign mass properties to shell models. To be able to do this you need to know the weight of the part and if you really do need to assign the centre of gravity then you will have to do this by hand and then assign it in the mass property window in SolidWorks.
Please have a look at the jpg which I have attached.
Hope this helps.
Kind regards,
George.
