FWIW, DRC now handles collisions with copper arcs, and zone cutouts for copper arcs.  

What’s still missing is the Connection Algorithm (because they’re arcs and not tracks).  That also means the DRC clearance calculations are one-sided as they only take into account the clearance of the colliding track or the zone (as the arcs are assumed to have a 0 clearance).

And then there’s the question of editing.  How do you drag tracks with curved corners?  Would one expect the PNS router to create curved tracks under some set of conditions?

Cheers,
Jeff.

When suggesting options for modifying class TRACK I got silence from the core devs and took the hint. C'est la vie.
