It’s also a cross-platform portable executable, so you can use it out of the box on almost any machine with an internet connection. Once you get the hotkey bindings down, it gets very easy to build simple designs. Unfortunately, it can choke on modest levels of complexity, but I most of my work is relatively simple, so Solvespace is a godsend.
Some friends of ours strapped down their roof for Hurricane Georges. They lived in a wood frame house on a hill and knew better than to just trust that everything would be ok.
Anyway, they still had a roof after the hurricane, but the winds were still strong enough to lift the roof up, damaging the joints between the rafters and the main posts holding the roof up. This damage I saw with my own eyes.
Wind shear can be remarkably strong at 140 mph, blowing across a roof like that. It would be a shame to lose the house because you didn’t take two hours to put some straps over it.
