precise scaling

[Da Vinci]

Hello friends, I make a synthetic example: I have a solid length 100mm. I want to climb proportionally and make it 81mm long. exists a command in rhino where I write 81mm and automatically the solid scale proportionally from 100mm to 81mm?
thanks to who will answer.

I believe there is no cad. the scale command always works with a factor, if from 100 you have to take it to 81 steps x a factor of 0.81.
