Backsplash and walls

[Staging Diva]

Hello,

I just purchased Interior Designer 9.0 today and am in the midst of learning the program. I have watched a few of the tutorials and while they give me the scope of what the program can do, they do not address specifics.

My initial questions are:

1) How do I extend the backsplash along the wall - specifically under a window casing and then above a set of base cabinets. I have tried to modify the counter with the backsplash options however the backsplash does not show up.

2) How do I get the walls from the other rooms to become transparent so that I can see through them and get a better view of my room? When I pan and move, they sometimes get in the way.

3) Any tips or tricks you might want to impart for a new user would be greatly appreciated. I have used many different types of software however they have not seemed as user friendly.

Thanks!
