Radius not matching with Physics2D.OverlapCircle

Hello, I'm very sure I must be doing something wrong, but for some reason,  when I draw a disc, the radius given doesn't match up with the overlapCircle or the drawgizmos. Both, the disc here and the gizmos have a radius of 5. 

Image 84

I'm not quite sure what I could be doing wrong. The prefab in use is scaled down to .6, but I wouldn't think if that was the reason the mismatch would be so much. The disc is a child of the prefab. I tried doing some multiplication as well to see if the .6 scaling was the reason, and I couldn't find a consistent multiple. Any ideas what I might be doing wrong?

if you really need to keep the scale of parent objects, then this might help compensate for it:
rangeCircle.Radius = towerModel.Range / rangeCircle.transform.lossyScale.x;

hm, weird!
are you drawing it with a component? if so, could you take a screenshot of the inspector?

if you're drawing it in immediate mode - can you show the code you use to draw it?

It's part a prefab. It's being drawn as a component, I'm setting the radius in code.

the component will be affected by the scale of all parents above, which I'm guessing is what happens?

Ah, ok. I pulled everything out and made it flat, the scaling was correct now. Maybe drawing in immediate mode would work better for me. You can mark this as answered. Thanks for this, this thing is awesome. I can finally move away from my terribly written shaders.

Oh wow that worked perfectly,  thanks for that.
