Hi All,
I have created some steps with two walls on either side. The problem I'm having is that because the top portion of both walls are semi-circular and forming a half tube each, the surfaces of their front side won't fill in. Please take a look at my attached file and help me fill them in. Also, if you are successful please explain what you did to fill in the surfaces. Thanks in advance.

Hi, thanks for replying. I tested your suspicion that perhaps the problems are caused by the fact that my walls do not have any thickness to them and found that it makes no differences either way. Regardless of how thick or thin my walls are it seems the PushPull tool extrudes rectangles instead of cutting rectangles. At this point I really don't know what else to do. In the Youtube video SketchUp: Making your own openings, the author said that the Push/Pull Tool should cut one face walls, and one face walls are what I had originally. Can you please try to recreate my problems by creating a one face wall and a wall with a thickness of 5" then cut windows in them. Thanks again for replying.

Please take a look at the door and windows and explain why the PushPull tool does not cut the walls all the way through. Thanks for your help.

Is there any way that I can upload my file so that others can see what I'm doing wrong? I've tried to use the "context-menu 'intersect' and make 'cutting' edges" like you've suggested but it too is grayed out.

Hi all, I am very new to Sketchup and in need of help creating openings in my walls.The video tutorials on creating windows and doors made it look really simple. All doors and windows were created simply by placing rectangles on a wall and then cutting out the area inside of the rectangles using the Push Pull tool. I don't know where I've gone wrong but the Push Pull tool extrudes instead of cut through the wall. I've read that this could happen if the wall's thickness is not uniform and that this could be remedied using the intersect command. I know for a fact that my wall's thickness is uniform because it is the default thickness which you'd get when you create a rectangle and then extrude it using Push the Pull tool. Also the Intersect Faces option is grayed out. Any suggestions will be greatly appreciated, thanks in advance.
