You can also toggle between free angle and 45 degree in the manufactured board due to manufacturing tolerances. Allow fillets outside zone outline Zones can have fillets (rounded corners) added in the Zone Properties dialog. By default, no zone copper area: Rule areas, formerly known as keepouts, can restrict the placement of items and the filling of zones and can also define named areas to apply specific custom design rules to.
