You will get used to the drilling down through the components, When you need to drill down just keep clicking on the selected area you want to edit and you will notice that blue dots will appear. This now means that you are now on the bottom layer of that component and you can now edit the face. This is the best way to start and is very easy when editing roofs.
Thats great to hear
Glad you love it. More tools that are even better are coming, stay tuned!
