Ability input additional values into VCB. For example, I move an object to a distance which I have referenced with mouse (click to click) then type “+100mm” to trigger 100mm moved further in same direction to the initial move. Simple math in VCB I know adding equation function into VCB can be tricky, but upon some testing, SketchUp does division well, then cannot do any multiplication? Input of “1000/2” works, b… --- _[View the full topic](https://forums.sketchup.com/t/be-able-to-type-in-simple-formula-when-entering-distances-and-scales-eg-1351mm-406mm/40271)._
