I am working on a design for a prosthetic socket liner. Right now the opening for the design is extended halfway down one side of it. I want to have just an elliptical shape as the opening on top. And I want it to follow the same angle as the axis 2 because having that angle there will allow the liner to bend with the amputee's knee a little better. However, I am having trouble creating the surface. I'll link you my part, as well as what a typical liner should look like. I've tried to use the lofted surface feature to no avail. Please let me know if you have any suggestions.
