Hello I’d like to export an animation from sketchup to blender in Blender I’d like to add something to it and then export it back to sketchup but is it possible???
I’m afraid you will be able to export the geometry and then import it back into SketchUp.
Anyway, why don’t you export the geometry from Blender and work in SketchUp?
You don’t need to export an animation to add something on blender, just import the model in blender, then export it and import it on sketchup. What do you need to add on blender by the way? Sketchup is capable of creating any kind of geometry you can imagine using the right tool.
