Centre of gravity

Hi someone

A quick question - can someone tells me how I scale a part in part studio around the Centre of Gravity? How do I set the CoG as reference point for scalling?

Thanks in advance

If the part is made of one consistent material, then you could use Transform scale + Approximate Centroid by @EvanReese

Sorry I am too inexperienced to understand this. I work in part studio and I cannot find anything about

Can you help a bit more? it is simply these two legs, which need to be scaled uniformly in all directions

It is a bit confusing at the moment without a Feature Store.

Go to the approximate centroid document, and near the top there is a (+) button where you can add custom features to your toolbar.

Fantastic - It works for me. This saves me a lot of time, great thanks

I see the benefit of these features - is there not at all a list perhaps unofficially or how can I search them out?

Here are all the different lists created by developers: Feature Lists.

The haystack method has a lot of good needles hiding in it.
