Hello sastun1962,

Ruler tool is designed for the measurement purposes only. So if you wish to scale the model based on some known distances in scene you need to create a pair of markers for each such distance in it's ends, create a scale bar between them and then input the known distance to the source values tab for the scale bar in the Reference pane.
