I would like model this seat. I'm using version 2.91 at the moment.
I have not found a way to smoothen the blunt edges. Currently this is the state of the seat:
Note that the edges are rounded in the initial image. How would one do this using the least complex method? I am fairly new to Blender, and am not yet familiar with 98% of the functions. I would also like to be able to make the corners rounded. Does anyone have any advice?
