[Center of gravity]

Use Inkscape:
Draw a path or use a shape converted to path
Then do
Extensions: Visualize Path: Measure Path
Set Measurement Type: Center of Mass
Apply

Red is rotated ellipse
Green is distorted duplicate
Blue is as green but with the hole

No idea about the accuracy, my days of calculating CoG's are long gone

Thanks! Great! Works!

Thanks! I left Inkscape for Affinity Design, but will check this out. Sounds good!

[Center of gravity]

Thank you Garry & NotMyFault! Background of my question is that I am constructing Mobiles. The elements for the Mobiles I cut out with a lasercutter. When using shapes like "plates" – see picture – or any other flat objects I have to find out the center of gravity. I am aware that I have the option to SEE the center of rotation (supposing that this is the same like the center of gravity), but I also want to MARK it. I can mark the center with the pencil, but then I have to enlarge a lot and the result is still not very precise.

@NotMyFault: I came across the NASA explanation. Thanks for that. But having a CAD app, a lasercutter and being not very good in math, I hope for a simpler solutiion...

Hi. How can I find (and mark) the center of gravity of a given 2D object in Affinity Design? Thanks. Christian
