Simple question I'm sure.

I'm sure this is simple, I just don't know how to search for it to read about it.

I am trying to draw windows out and the subtract them from the wall but like the picture shows I try to select the square(circled) and it selects the whole rest of the wall. I don't understand what I am doing wrong.

Try to re-trace the edge that is common with the wall face. It seems that for some reason, it didn't merge and doesn't separate the faces.
If no success, attach the file.

Thanks! You remind me of my own newbie frustrations.

These problems always come from lines that look planar, but aren't quite planar. Here are some tricks for being perfectly planar.

Rectangle on the rg (ground) plane. Pushpull up for a nice, big box. Triple-click to select all. Right click, Group. You now have a drawing surface. Rectangles and Lines drawn on this surface will be perfectly planar. Because it's a group, click to select and Delete to erase it, but leave your lines.
Architecture: Draw a rectangle on the ground. Use the oFFset tool (tap F on the keyboard) and drag inside. Type 6, Enter, for six-inch walls. Pushpull up the walls. Rectangle doors and windows on the walls. Pushpull them out.
Use the Tape to create construction guides. Intersections of these guides are quick and reliable.

Here are some tricks for guaranteeing problems.

a) Use Lines to draw walls.

b) Draw Lines without using inference points.

c) Visually inspect, instead of using the Tape.

Thanks for the responses, they where quick and helpful but I guess I can't wrap my brain around them. I got one side to work but with a lot of cmd-z and reworking.

I thought I was making all the squares planer on the end, by making a square from the endpoint and then using another endpoint and typing out the dimensions but I guess that doesn't make them right. Because it still will not select just the squares.

EDIT:
I think I might have actually figured it out, I tried the making a big rectangle to use as a drawing surface and that is working now. I believe I was just using the "move" tool wrong. I wasn't select the end points to match up with the end point of the previous square I had place. Hopefully that make sense.

Out the squares
Click the wall : hide
Click the wall : hide

you will see that the squares are not drawn on the same level
some are transparent some are reversed somme are full ...!
It's the mess
if you want move someone just group them & move

that you must make from the beginning
draw one :group it, copy move with snap
(or make component if you want an elaborate model with possibility of change)
At the end group all et voilà
Name group is a good thing for use after the Menu Window/Outliner for an easy selection
