what I learned during ICT class in this week

So this week we are learning about Google Sketchup.Which we mainly learned about how to make windows by using half-half windows cover each other and make a rectangle in the middle. And other things after that I actually learn how important the button the called "make component" mean which when I forgot to make component on an object before do something else and that really messed things up so I got to reopen the save file again so I need to start to save after when I done with make an object successfully first so I could go back not too far from what I done wrong. And this week we will make door's handle which circles are hard to make in this program.
