Grasshopper Scale

Is there a way to use Grasshopper in Rhino to accurately scale a 3D shoe model from size 8.5 UK down to 5.5 UK? I find the Scale 3D command not really accurate.

It should be as accurate as your Factor + model tolerance. share a script or a dummy model so people can help you.

Scale 3D

What is your model tolerance? I see that you are comparing topologies but really not sure how are you aligning them.also I feel the z value difference happens because you used the scaling center point on the cplane.
