WN, Thank you so much for providing me with four different ways to do this.

I was able to obtain a solid using each method after watching the video.
It was a demonstration on a model that I could actually access, so it was more informative than any YouTube video!

I understand that Phiro's method is the second method, and BurrMan's method is the third method.

My mistake was to stubbornly try to create a solid under the zigzag solid. Only the fourth way is such an approach.
I also made the mistake of using "Edit | Join" to join each surface to get a solid.
I learned that the correct way was to use "Boolean | Join" as shown in the video.

I've been using MoI for about two years now (= my CAD experience). Dismantling the bottom of a solid to make it a joined surface and then adding other faces to create a new solid was a fresh approach for me.

I usually make simple models or models using Revolve, and I'm currently studying to make a cutter as part of my skill improvement.
This part is the grip of the cutter.

Thank you, Phiro and BurrMan. I was able to understand thanks to WN's video. :)
