Creo Live Simulation allows the user to set the top and bottom of the scale. I suggest that the user should be able to use any color division or at least orange to red to set the scale. The reason for setting the scale is to visualise where the stress goes beyond a defined limit. Setting the top of the red scale does not provide a delineation at the defined limit. To get this the user must calculate the scale settings required to get the required value at a delineation on the scale.
To set delineation between orange and red:
((Required value - bottom of scale) / 8 * 9) + (bottom of scale)= top of scale
Make setting of scale to needed values simpler. The computer is much faster and better at making these simple but time consuming calculations.
