I have been using Blender for about a year and I sill don't know much. I was recently messing with the curves and watching tutorials when I stumbled into something weird. When I added the curve modifier to my shark and binded it to the curve the shark turned into a whole new shape, and when I tried shrinking it, but then my shark was 2d. If anyone knows anything please help me.
Actually I got it to work by redoing the curve, but I ran into a different problem.
