Radius Change - Simple Tube/Pipe Geometry
I have a simple geometry of a tube in a U shape. I want to change the radius of the tube but keep the internal and external diameters of the tube the same. I want to set this as a parameter, although this isnt the problem for me. I am struggling to change the radius of the bend whilst keeping the straight sections parallel. Any help is much appreciated.
Please see attachment for the problem geometry.
