Centre of gravity

Rhino
1

Hi all,

I’m working on a sterling silver coin pin and i need to find the centre of gravity on the object to add a hole for the pin mechanism. (the pin wont be printed - just added after manufacture)

what commands do i use and how - i know of VolumeCentroid - but im not sure what to do with the numbers it produces

thanks

IIRC that command also creates a point at the centroid (possibly requires a command line option?).

OH! it does literally create a point… i didnt see

Is your part completely homogenous?

If not, you can use the described method but make sure to weigh your part CoG coordinates by the mass of each part and the result for the final assembly’s CoG can be calculated like that.

I use Grasshopper for this, the Volume node provides the centroid that you can deconstruct and weigh.
