Something was changed in SketchUp 2022, that still would show as a difference for you going from 2021 to 2023. When in Parallel Projection Zoom Extents, and when orbiting, the camera is backed outwards to prevent clipping. If you have a use case for needing the camera to be in the middle of the geometry, facing a given direction, and with Parallel Projection turned on, you can still do that by using the Position Camera tool. Save the scene at that point, and don’t orbit or zoom extents after that.
For a case where you have a 2021 file that was working ok with LayOut, there is a Ruby script I put in this topic that will adapt the scenes so they still work:
That doesn’t help you though. If you could work in non-Ortho in LayOut, you could view from anywhere, but if you need Ortho, then the problem is that LayOut doesn’t have a Position Camera option.
I will tag @trent so that the LayOut team realize that the missing option means you’re going to have to stay with using 2021.
