In the components window, right click on the component to be replaced (sphere), choose "Select Instances". Find the component you want to replace it with in the components window (ball), right-click and choose "Replace Selected" and it will replace them all at once.
Is that what you meant? If you mean a plugin that would let you replace all the spheres with balls and all the cubes with players at the same time, that would be more complicated than doing it the manual way with the built in tools in SketchUp.
I know the method with the components window but I meant the second thing you said. I was wondering if there is any plugin or method that can replace all the cubes with players and all the spheres with balls both at the same time.
But thanks for your answer!
