I was modelling a stone bridge for about 45 minutes (restarted design a few times) and suddenly, when I was finally content with the basic layout thus far, I tried to extrude the top and it refused. It technically extruded, and the numerical location indicator in the bottom left said I was moving it, but still the extruded region remained in place. I tried rotating which did nothing, and scaling brought them all to a point, as though I had tried to scale and pressed 0. Any ideas? Thanks in advance.
Sure it’s not that big of a deal and the bridge is a simple design I could remake in a short amount of time, but I’d like to know what I did wrong, if anything, to prevent this in the future.
