Scale text and drawing to new scale

Hello. I am drawing in Sketchup and have put my object into layout. I have made text to describe my project in deatil. However i have drawn in scale 1:50 and would like to change into 1:100. Is it possible to "scale the text and arrows similary, so i dont have to correct them manually afterwards?

Thanks. Isak

Text size in LayOut is independent of the view scale so if you want to change the text size of your labels select them and use the tray. Text labels in your SketchUp model also retain their screen size independently.
