You will find included in your template the following angled support beams both at 75 mm and 65 mm width's; 67.5, 60, 45, 30, 22.5 degree angles. Most balsa bridges are types of truss bridges or arch bridges, as the wood lends itself well to this type of construction. Some filters moved to Formats filters, which is at the top of the page. Using the ctrl c and ctrl v will allow you to copy required support beams rather than have to make them.
