In the last couple of after dark videos Al does swept surface. It is my understanding that swept surface is for all purposes an ' extrude curves/shape' but along a path that doesnt have to be linear. Also swept geometry wont be capped as it isnt a surface.
My question about the videos is Al has the geometry/shape in the same plane as the path/trajectory. To me that would result in a plainer shape. But the end result is as if the shape is normal to the end of the path. How the heck does he do that and if there is something I dont under stand about the geometry and path in one plane generating a 3d shape, how do you clock the shape around the and of the path line?
