Best way to lay vertical trimmed surfaces flat and arrange them in Rhino

[Patricia4 (Patricia)]

Hello, I am a beginner in Rhino and only use a very small part of the program for my work.
In my project, I have created vertical sheet elements from trimmed surfaces. Now I would like to lay them flat on the “ground” and arrange them next to each other in the simplest way possible.
Unfortunately, I haven’t been able to find a quick and easy workflow for this on my own. Could anyone please help me with this?

The first picture is how I would like to have them and on the second picture is my starting position.

Best regards,
Patricia

Rotate them around the x-axis by 90° with BoxEdit with the Use bounding boxes and the Transform objects individually option. Then you Move them around freely or with a snapping option.

Next time, better take screenshots instead of taking photos of your screen. Photos are blurry and some possibly essential details aren’t visible. It often also helps to include the .3dm file.
