Extrude along curve / sweep

Thanks Pascal. The shape you produced is perfect, but I am not able to use sweep and produce that result. (I have never used sweep before.) Could you possibly provide any more specifics on how you did it or a quick video, or point me to a video that might help?

Also did you understand the second question? It was about resizing the panel horizontally without changing the width of the vertical rails. Are there any commands that come to mind for that? Otherwise I have been recreating the panel at the new width so the vertical rails don’t change width.

Thank you!
Sarah
