I want to make my model "4cm" in order to be able to 3D print the model. I've applied the scale of my model, and I am trying to change the dimensions of the Y-AXIS from 11.817 m to 4cm, while the other X and Z axis scale proportionally. But, I the X and Z dimensions don't scale to their proportional sizes to the Y-Axis of 4cm, and turn into X:0 and Z:0 . Is there anything im doing wrong? or another way?
