Joins all listed solids into one (the minimum of their fields). The blend type and radius shape the seams where they meet. A blend also swells a surface the solids share, such as an infill reaching a shell's outer skin: cut the result with the part (Intersect) to keep that skin where it was.
The solids to operate on: fill in the rows, or wire a Solid list in their place. For Cut these are the solids removed.
Shape of the seam where solids meet: rounded (circular fillet), chamfered (45° bevel), sharp (no blend; the radius is ignored), continuous (polynomial smoothing), organic (exponential melt; shifts the whole surface slightly, not only the seam) or super (superelliptic fillet that joins with continuous curvature, so no edge line shows; surfaces farther than the radius from the other solids stay exactly as they were).
Blend radius in mm. Wire a field to vary it across space; wherever it is 0 or less the seam stays sharp. Ignored when the blend type is sharp.
Values the block gives besides its output. The editor lists them under Properties, and an input can read one by reference.
The axis-aligned extent of the Solid.
The Solid's signed distance, as a field.
The Solid turned inside out: what was inside is now outside.
