I'm working on a 3D version of my company logo (file attached).

I have tried a few techniques to build this wave design, and settled on constructing it as two networks, then Union.

The result is fine and renders OK. But I'm still learning and wondering if it could be constructed as a single object. The lower "branch" seems to be the challenge.

I originally started with just an extrusion of the overall 2D shape and would be happy to just fillet the perimeter. However, due to the point of the "branch" I can't get a fillet.

The 2D illustration I'm using as a guide shows some beveling. I'm not trying to reproduce this feature. I'm just want rounded edges to pick up highlights for the render.

Any ideas are welcome.
