Resizing a curved object

I have half of a mold of a small guitar, I need to size it proportionally. No matter where I select to scale the object it doesn’t the whole piece, one areas always wider.

What I need it to size it bigger without any distortion, but I can’t seem to find a way to do that.

Thanks

Hi Paul - the Scale command should do what you want if it is a scale and not an offset that you’re after…

Offset?

I want about 30mm between it and a copy of it, think of an inner shape and an outershape that are consistently a distance apart all the way around…

I’ll have to go look up offsets…

Thank You

That was what I was looking for, thank you…
