Hello,
I am working on a document with different options of the same plan.
I have 1 option by scene.
I keep the same view scene by scene to facilitate the work and then export easily to layout.
However, by mistake, I refreshed one of the scene 
How can I get back to the original view or the same view as the other 3 scenes ?
Is there a way…?
Thx,
Maya
PS : I added a video to make it clearer 
Hello,
Hi Paul !!
Thanks for the very clear video 
All OK now !! 
THANK YOU !!
@paul.millet has answered this. But you can also do it even quicker by these steps:
In this video I am copying Scene 2’s camera position to Scene 1.
This is also a quick way to update the camera on any scene you are viewing - just reposition the camera as you want and uncheck and recheck the “camera” attribute.
Thank you very much for sharing this other technique
Indeed very quick !
This brings up something I’ve noticed over the years. Undo and redo only work on modeling, but any change to shadows, scene, styles, anything, is totally ignored! So if you do change a scene or time, there is no way to revert. I find this borderline close to an actual issue sometimes.
Hi Dave
When you have a minute, can you explain how to create the greyed out background view I have highlighted below please.
Thanks 
Hi Kevin. Stacked viewports using the same scene with a rectangle with transparent fill in between. The elevation scene has an active section plane but the style for the scene has section planes, cuts, and fill turned off. For the top viewport in the stack I turned off tags/tag folders for everything except the carousel horse. For the bottom viewport in the stack, I selected the Hidden Line with Section style from my collection of styles I use in LayOut projects.
Here I’ve colored the rectangle and made it narrower so it doesn’t cover the entire lower viewport.
FWIW, the one to the left is also stacked viewports of the same scene. The top one has the Hidden Line with Section style and then a circular clipping mask to make it look like there’s a hole through the siding. The bottom viewport uses the default settings from the scene.
Thanks Dave.
I am going to experiment with that in the morning. I have often wondered how those scenes are created
Sorry if this has been covered and I’m repeating, but I couldn’t see any reference to the Scene Tools plugin.
Extension | SketchUp Extension Warehouse
It has some great options for copying camara views, layers (or whatever they are called post 2018 Pro version), styles and a few other features I don’t regularly use.
May not be as quick as some other suggestions and better features available post V2018, but I’ll give kudos and recognition to the author of the plugin (Didier B., I thank you!).
Theres actually another way too, but I dont have screen recording software. You can select the scene which is the correct view you want, then go to the scene which is the problem and immediately press the “undo to previous camera view” tool and then refresh your scene
I find Julia Eneroth’s “camera memory” incredibly useful for this workflow.
It even works between different files - my use case often involves very heavy files with different iterations of designs. Sometimes I have to go back to an older design and use exactly the same view.
