As the Altium article correctly states there is a point for manufacturability of sharp corners, and their tendency to cause acid traps during etching. I haven’t seen any problems with that in the last decade with 6/6 mil spacing boards though. I guess it might still be a problem if you’re designing/manufacturing iPhone pcb’s.<br class=""><div><br class=""></div><div>Also, 45 degree corner is a misnomer in this context but everybody seems to call it that way historically.
