Hello everyone, 

I'm an industrial design student in Australia trying to create a lampshade for university. Using Solidworks 2021 premium. 

I'm looking at creating a cylindrical ribbon-type shape and manipulating it, while maintaining the width and length of the surface. 

I want to bend/flex one side of the cylinder, while leaving a portion of the cylinder in the same place. 

I have tried a bunch of ways to do this: 

• Surface loft
• Flex tool on surface body
• Surface Sweep with 3d-sketch guides. 
• sheet metal functions
• Wrap feature on solid body (most successful so far).

I was posting here to ask what would be the best way to do this? I have had moderate success with the wrap feature but it wigs out when the length of the strip approaches the full required length for the ends to join back up. 

It is worth noting that I am trying to replicate the way that surfaces of a cyclinder 'dip' in the y-axis (up n down) when manipulated in this way. I also need to make sure that the top and bottom edge-lengths are equal, as well as the height of the surface all the way around. See real-life images for an example of this. 

Thanks!

Nicholas.
