What is the best way in VS to create these shapes?

[Boldline]

Does anyone have any suggestions as to how to create these shapes and specifically the corners I circled? I want to be able to easily give it the "wrap around look", but not have to do it by hand each time. Thanks!

​I'm not really sure that I understand what you want
but how about this approach?

@Boldline Those kind of 3d rendering looks will always be hard to achieve in a drawing app. Maybe using mesh gradient.

Added to my Shape from above a Bevel Effect for 3D
and a little Stroke with a Profil and a Gaussian Blur Effect
to fake the Light
