I have a need to merge multiple objects into one. But this is more than a boolean operation - I need them to sort of weld together. It's probably easier to just show an image.

Note how the intersections are smoothed, it's a solid object, and the edges are crisp and straight. What you see is the power of Power NURBS/Power Booleans. But my needs are several orders of magnitude more complex than that can handle.

There used to be a plugin called Clay Studio Pro that did what I need, but it is now defunct, and I need a replacement.
