When I save scenes, I always use “zoom extents” to make sure that scenes will align in Layout.
How I do it:
for example you have two objects, A and B.
Delete B, use “zoom extents”, save as scene 1.
press “ctrl+z” to recover B,
delete A, use “zoom extents”, save as scene 2.
press “ctrl+z” to recover A.
Save the file.
This is an easy way to make sure your scenes will perfectly align in Layout. It worked in any previous sketchup versions.
But not in 2021, when you try to save after you created the scenes, you will find this model is “beyond repair” or “unable to save your model.” or Sketchup collapses immediately.
Does this happen to anyone else?
