Ants: routing and our own terms (from Nov 2026)

Pull-tight

The cleanup pass that straightens a routed track off the grid into clean 45 degree runs, as short as the rules allow.

How it looks

Real image: CORE3588, rendered by KiCad from our board file

Finished tracks on CORE3588, top side, 14 x 10 mm, routed by hand by Sam. Pull-tight aims for this look automatically.

1A bundle of tracks running at 45 degrees, side by side at the minimum gap.
2Each turn is a 45 degree corner, never a right angle; this is what a pulled-tight route looks like.

Pull-tight is the last pass of hybrid routing; a topological router does a similar "rubber band" tightening.
