This is the first chair that I created in tutorial 4. It is called subtractive because you draw simple shapes and then subtract other simple shapes from them to create the object.
This is the 2nd chair that I created in the 4th tutorial. It is called additive because you create simple shapes and add other simple shapes on top of them to create the object.
I learned in the 3rd tutorial how to create shapes within shape and how to create cutouts. Cutouts can not be created on sides that do not have parallel edges or egdes running through them.
I also learnd how to move edges diagonally in tutorial 3. To move the entire object, I must select the whole object using the selection tool and use the move tool to move it.
The first tutorials taught me the basics of sketchup. Draw a shape, pull into 3D, and repeat were the basic ideas of sketchup. I also learned about the orbit tool, zoom tool, and pan tool.
The second tutorial taught me how to successfully create edges. This was a lot harder than it initially looked because of the different planes that you can draw on. This tutorial was very helpful in teaching me how to decipher which plane that I was drawing on. I also learned that you can only draw edges from one existing edge to another. You can not draw through existing edges.
