You’ll just have to scale it larger once you start working on the actual installation. It is free software, you can change its source code and distribute your changes. GIMP is a cross-platform image editor available for GNU/Linux, macOS, Windows and more operating systems. Even if you're planning on making a large sidewalk drawing, starting with these graphs can help you plan out your design. This is the official website of the GNU Image Manipulation Program (GIMP).You may want to label the rows and columns with numbers and letters to help you keep track of each square.The number of lines you’ll use will depend on the size of your drawing, but for a simple sketch, a 5x5 grid is a good place to start. Don’t make the squares too small, or it will be hard to see the details of your drawing.

The more dramatically you angle the lines, the larger the object will seem. The bottom of the graph (typically the part closest to the photo point) should be the widest, then it should become more narrow the further up the page it goes. Once you know where you want your photo point to be, use a ruler to draw a graph with angled lines so it looks like the graph is trailing into the distance. Draw a line graph with vanishing perspective lines.
