I am very new to Sketchup, and in my first project i am having problems with cutting out windows using the push/pull tool (see my problem in the attached picture) It does not seem to cut all the way through, even though i have alligned it with the other side of the wall. Can anyone please help.
Most likely the window plane is not parallel to the wall plane.
Or the far side of the wall is not parallel to the near side. If you upload your skp file here, we can tell you for sure.
