Problem: Article: Use a pencil and a ruler to draw out a square on a sheet of clean paper. Hold the ruler in your nondominant hand and use the side of the ruler as a straight edge to draw each side of your square. Make your square 7.7 by 7.7 centimetres (3.0 by 3.0 in) to create a scale model of the Great Pyramid! Every 1 centimetre (0.39 in) will represent 30 metres (98 ft) of the pyramid. Use your ruler to calculate the midsection of each side of your square. Mark the spot where you need to place each line with a small hash mark and then rotate your ruler to draw each line perpendicular to the square's side.  For the Great Pyramid scale model, place each line 3.85 centimetres (1.52 in) in from the corner of each side, and make it extend 6.2 centimetres (2.4 in) out from the square. If you're not building the scale model of the Great Pyramid, you have to draw each line so that it's big enough to meet the other faces of the pyramid in the center. To be safe, make each line at least the same length as a single side of your square. Use your ruler to line up a connection between the top of each line and the corner on each adjacent side. Start at the top of a line and draw a connecting line to the corner of the square on the left. Draw a symmetrical line going from the top of the line to the corner on the right. Sketch your lines out using the ruler and pencil until you've drawn 8 connecting lines to their corresponding corner on the square.  You should now be looking at 4 triangles that share a base with the 4 sides of your square. For the scale model, each connecting line should be 7.3 centimetres (2.9 in). Hold the paper in your nondominant hand and use a pair of scissors to cut along the exterior edges of your shape. Continue cutting along the edges until you've cut out the entire drawing. It should look like it was cut out in one continuous cut. Lay your cut-out shape flat on your work surface. Use your nondominant hand to brace the paper along each side of your square before folding each triangle towards the center. Use the pad of your finger to firmly press down along each fold. Continue until you've folded every side of your pyramid towards the center. You can fold each face so that it lays flat in the center before folding the next section if you want to get each side out of the way. This may make folding much easier. Pull each folded edge out until each triangle is sitting flush against one another. Use clear tape to permanently join each edge together. Use long pieces of tape, and put each strip on the side of your triangles at the line where they meet one another before pressing lightly along the sides. Press your tape down slowly and delicately. There's nothing but air inside your pyramid, and you don't want to crush it while you're taping it. Place your pyramid in a small, plastic sandwich container or paper plate to catch the sand that you're going to pour over the pyramid. Use a paintbrush to apply white glue to each face of your pyramid. Spread it liberally across each visible surface until the entire structure is wet. While you certainly want to cover each side of your pyramid, avoid using heavy globs of glue. You don't want to weigh your pyramid down and ruin the paper. Slowly pour sand over the top of your pyramid, covering each side of the structure as you pour. Use a spoon to scoop sand that falls to the bottom of your container on top of the areas that are missing sand. Repeat this process until each section is fully covered. Wait 45-60 minutes for your pyramid to fully dry before handling it.
Summary: Measure and draw out a square using a pencil and ruler. Draw 4 symmetrical lines that start on each side of your square. Connect each line to the adjacent corners with your pencil. Cut out your pyramid carefully with a pair of scissors. Fold each face of the pyramid towards the middle. Tape the edges of the pyramid's faces where they meet. Cover your pyramid with glue to add sand if you want to make it realistic. Sprinkle sand over the top of your pyramid.

In one sentence, describe what the following article is about: Scroll over to the tab for the Build mode part of the catalog. Hit the X button to select the Walls and Fences section. This opens the removal wall and fencing tool. Now that you have the wall tool available, move it to one of the corners of the wall or the spot you wish to remove. First, press the X button. Then, stretch this wall tool out to cover the area you wish to remove by using your Left Analog stick till you have sufficiently covered the amount you want to remove. Notice that it has all X's on it and that it is green. This means you have selected to remove a wall or a fence and it is allowing you to do so]. Press the X button again to remove the wall section. Just hit the Triangle button to exit.
Summary:
Select "Walls and Fences". Now hit the Square button. Place the wall tool where you need it. Stretch the wall tool to cover the entire section you want to delete. Delete the wall.
