Success! Thanks again

^Thank you! But when I do that, only the faces remain, but the wall thickness disappears? The faces of the inside walls are gone. Am I doing something wrong?

Sorry if this is in the wrong forum! If there is a tutorial on this, please direct me to it.

So, I just read the "How a Pro Builds a House in Sketchup" tutorials a few days ago, and it has helped a lot! I have a problem that the tutorial doesn't address - adding a roof. I raised my walls and now, it's just a bunch of walls with nothing connecting them. I've tried using the rectangle tool to fill in the spaces, but then on the roof, I see the lines of the walls that have been raised up.

Can someone please explain to me how I can make a flat roof without the lines showing?

So, I've drawn out the floor plan of a building, and am using that to make my walls using push/pull. Once I got the walls to the right heights, I covered the top using the rectangle tool. The problem is that I have my roof, but you can see the floor plan from the first floor drawn on it because of the walls! How can I get rid of those lines without destroying the walls and their thicknesses?

Thanks!

Why is it that when using the pencil tool, some lines, when drawn, are "normal" thickness, but some are very thick? I use the same settings for both lines too. I am trying to separate the panes of a window by drawing in lines, but one line is normal (the first on I draw), but the second one I draw is very thick. Any help?
