I ran the old sherk2 script again, and applied some different MoI commands.

Lineweb will form a curve between the endpoints of a bunch of curves originating from a single point, with point count = 2.

Rather than arc, Blend was used to connect the ends, then Join. The long lines were trimmed.

Network then works quickly.

Each blend arc and face was then deleted with a plane.

Move and rotate then extended the Sherk2 surface.
