@Rich-O-Brien so i understand that it may make the joinery hard to pull off but my goal is to create a cnc ready file and since sketchup is the only 3d software i know i figured i would start here. Ill try your suggestions

Here are some more pictures. I am using Sketchup Pro 2023.

So i am trying to design a guitar pick stool with maloof joinery and i am having trouble with shaping the top. Can someone tell me how this is done. Here is a link [https://www.canadianwoodworks.com/cdn/shop/products/Guitar_Pick_Stool-9.jpg?v=1566855373] to what i am trying to accomplish.
