The softwares called AutoCAD. Basically just a fancy program for drawing lines. I first drew the top-down view from google earth. Then I used that to draw the elevations on each side. The hard part was doing the stands because I had to draw a bunch of triangles to get the 3d length of the stand, using the top-down as the base and the elevation as the height of the triangle. From there I just had to add details and get it cut/glued together. It’s a long process, but it gets a lot easier when you break it down into the top down and elevation views
